Claude Sonnet 4.6's response to the 'Historical Counterfactual Analysis' challenge.
If the transistor had been invented in 1920 instead of 1947, trace the likely technological, economic, and geopolitical implications through 1980. Be specific about second and third-order effects. Consider: How would this affect WWII? The Cold War? The space race? Consumer electronics? The structure of major economies? Which countries would benefit most? What technologies would emerge earlier, and what unexpected consequences might follow?
This is a serious analytical exercise, not science fiction. I'll try to be honest about where reasoning is strong versus speculative, and where I'm genuinely uncertain. The goal is to trace mechanisms, not just assert outcomes. Some conclusions will be counterintuitive and I'll flag where I'm making judgment calls that reasonable analysts might dispute.
The first honest thing to say is that the 1947 transistor wasn't just an idea — it required:
A 1920 transistor is therefore not simply "the same invention, earlier." It would likely be:
This matters enormously for diffusion speed. The historical transistor benefited from a rich theoretical framework that allowed rapid improvement. A 1920 transistor would likely see a 10-15 year lag before reliable manufacturing, meaning practical applications might begin around 1930-1935 rather than immediately.
I'll call the invention itself 1920, first reliable manufacturing 1932, and first widespread commercial deployment 1936-1938.
In 1920, the organizations capable of recognizing and exploiting a transistor-like device would be:
AT&T/Bell System — historically the most likely host institution. They were already deeply invested in vacuum tube amplification for long-distance telephony. A solid-state amplifier would be immediately recognizable as commercially valuable. They would likely patent aggressively and sit on it initially, exactly as they sometimes did with threatening technologies.
Military signals establishments — the U.S. Army Signal Corps, British GPO, and German Reichspost were all sophisticated consumers of amplification technology. They would recognize military communications applications.
Radio manufacturers — RCA (founded 1919), Marconi companies, and others were in a fierce commercial battle. A solid-state amplifier that didn't require the warm-up time, fragility, or power consumption of vacuum tubes would be immediately attractive.
Germany — Weimar Germany had excellent physics and chemistry infrastructure. Siemens and AEG were world-class. If the invention happened in Germany or was quickly disclosed there, German industrial exploitation could be rapid.
One underappreciated consequence: in 1920, patent law and corporate IP strategy were already sophisticated. AT&T in the 1920s was already engaged in cross-licensing arrangements with RCA, GE, and Westinghouse that essentially divided the electronics market. A transistor patent would enter this existing cartel structure.
Likely outcome: The transistor gets licensed within the existing cartel, development is slowed by corporate strategy, and the technology remains expensive and controlled through the 1920s. This is actually what happened with many interwar technologies — the cartel structure retarded competition.
Second-order effect: The radio boom of the 1920s is somewhat different. Crystal sets (which used a crude semiconductor detector) were already popular. A transistor-based radio would be more sensitive and reliable, potentially accelerating radio adoption by 3-5 years. But the bigger consumer electronics revolution would wait for manufacturing cost reductions.
The 1920s U.S. economy was already experiencing a technology-driven boom (automobiles, radio, electrification). Adding transistor electronics to this mix:
The more interesting economic question is what happens to the vacuum tube industry. In our timeline, vacuum tubes were a major industrial sector employing tens of thousands. Early transistors would threaten this, but given the manufacturing difficulties of early solid-state devices, vacuum tubes would likely survive through the 1930s in many applications. The disruption would be gradual rather than sudden.
This is where the timeline diverges most dramatically from our own.
In our timeline, the first electronic computers (Colossus, ENIAC) were built in the early 1940s using vacuum tubes, specifically because vacuum tubes could switch fast enough for computation. Mechanical relay computers (like Zuse's Z3) predated them.
With transistors available and improving through the 1930s:
By 1935, Bell Labs or a university research group would almost certainly attempt a transistor-based logic circuit. The conceptual leap from amplification to switching is not large — engineers would make it.
By 1938-1940, a working transistor-based digital computer becomes plausible. Not a modern computer — probably a special-purpose calculator with hundreds of transistors, slow by later standards, but dramatically more reliable than vacuum tube equivalents.
Critical difference from vacuum tube computers: Early transistors ran cooler, used less power, and were more reliable. The fundamental problem with ENIAC (18,000 vacuum tubes, constant failures) wouldn't exist in the same form. This means:
Who builds the first transistor computer?
The honest answer is: probably the United States or Germany, and probably with military funding.
In the 1930s, the U.S. military was not particularly forward-thinking about computing. But the Census Bureau and insurance actuaries were already interested in mechanical computation. The National Bureau of Standards would be a plausible host.
Germany is actually a strong candidate. Konrad Zuse built his Z1 relay computer in 1936-1938 in his parents' living room with minimal support. With transistors available, Zuse or someone like him might build a working electronic computer by 1937-1938. German industrial firms (Siemens, AEG) would recognize the application.
This is a genuinely important divergence point.
By the mid-1930s, with reliable transistors:
Portable radio becomes practical. In our timeline, portable radios required heavy batteries because vacuum tubes consumed substantial power. Transistor radios (our timeline: 1954) would appear in this alternate timeline by approximately 1937-1938.
Implications:
Long-distance telephony improves significantly. AT&T was already the primary beneficiary of vacuum tube amplifiers for transcontinental calls. Transistor amplifiers would reduce costs and improve quality, potentially making international telephone calls commercially viable for businesses (not just governments) by the late 1930s rather than the late 1940s-1950s.
Radar development in our timeline occurred roughly 1935-1940, with operational systems by the Battle of Britain (1940). Radar required:
Transistors of the 1930s would likely not be fast enough for the highest-frequency radar applications — this is an important caveat. Early transistors had frequency limitations. However, they would improve receiver sensitivity and reduce the size of radar equipment substantially.
More important: Transistors would accelerate the development of electronics theory and practice generally, meaning that by 1935-1938, the engineering talent pool capable of building radar would be much larger and more sophisticated. Radar might appear 3-5 years earlier — potentially operational by 1935-1937.
Let me be clear: transistors don't prevent WWII. The war's causes were political, economic, and ideological — the consequences of WWI's settlement, the Great Depression, the rise of fascism, Japanese imperial expansion. Electronics doesn't fix any of this.
However, the conduct of the war changes substantially.
Germany in the 1930s had world-class physics and engineering. However, the Nazi purge of Jewish scientists beginning in 1933 was catastrophic for German science — Einstein, Franck, Born, Szilard, and dozens of others left.
Transistor-related question: Would the Nazis have been better or worse at exploiting transistor technology?
Argument for "better": Germany had excellent industrial firms (Siemens, Telefunken), strong engineering culture, and by the late 1930s, massive military investment in electronics.
Argument for "worse": The brain drain was real and devastating. Many of the physicists who would understand solid-state electronics most deeply were exactly the people the Nazis drove out. Moreover, Nazi industrial planning was often chaotic — competing fiefdoms, ideological interference with science, and the "wonder weapons" mentality that prioritized dramatic projects over systematic development.
My assessment: Germany might have better transistor-based military communications and computing by 1939-1940 than the Allies, but would fall behind by 1942-1943 as the Allied industrial and scientific base — augmented by European refugees — caught up and surpassed them.
In our timeline, Britain's Chain Home radar system was the decisive factor in the Battle of Britain. With earlier transistor development:
Britain: The British were already sophisticated about radar. Earlier transistor development would likely mean a more capable, more portable, and more integrated air defense system. The Chain Home system might be supplemented by mobile radar units and better airborne radar by 1940.
Germany: The Luftwaffe's radar development (Freya, Würzburg) was actually quite good in our timeline. With transistors, German radar would also improve. The relative advantage might not change dramatically.
Net assessment: The Battle of Britain outcome is probably similar — Britain wins — but with fewer aircraft losses on both sides due to better radar on both sides providing more warning time. The campaign might be shorter.
This is where transistor technology would matter most for WWII outcomes.
Communications: The Wehrmacht's tactical communications in our timeline were already quite good — they had excellent radio discipline and used combined arms effectively. Soviet communications were poor, contributing to catastrophic losses in 1941.
With transistors:
The Soviet problem: Soviet electronics in our timeline lagged badly. They were dependent on captured German equipment and Lend-Lease for much of their communications technology. With transistors available since the 1930s, the Soviets might have invested more heavily in electronics manufacturing in the Five-Year Plans. Stalin's industrial planning, whatever its other failures, was capable of prioritizing specific technologies.
Plausible scenario: Soviet transistor production by 1940 is modest but growing. By 1943, with massive wartime investment, Soviet field communications improve substantially. This partially offsets the German tactical advantage.
Cryptography and intelligence: This is perhaps the most important second-order effect.
In our timeline, Bletchley Park's breaking of Enigma was decisive. The electromechanical Bombe machines used to break Enigma were the direct precursors of Colossus, the first programmable electronic computer.
With transistors available:
Japan is an interesting case. In our timeline, Japan had excellent naval technology but lagged in electronics compared to the United States and Britain. Japanese radar development was poor; Japanese communications security was weak (the U.S. broke Japanese naval codes).
With transistors available since the 1930s:
Key divergence: The Battle of Midway in our timeline turned on intelligence (broken Japanese codes) and luck. With better Japanese communications security (transistor-based cipher machines), the intelligence advantage might not exist. The Pacific war might be longer and more costly.
This is a critical question: Does earlier computing accelerate the atomic bomb?
Yes, but not as much as you might think.
The Manhattan Project's computational bottleneck was real — calculations for implosion lens design and neutron cross-sections were done by teams of human "computers" with mechanical calculators. ENIAC was actually completed after the first bombs were used (ENIAC: November 1945, Hiroshima: August 1945).
With transistor-based computers available by 1940:
But: The Manhattan Project's real bottlenecks were material (producing sufficient U-235 and Pu-239) and organizational, not computational. Computers would help but wouldn't transform the timeline by years.
Europe: Germany still loses. The fundamental problem was one of resources and coalition — Germany could not sustain a two-front war against the combined industrial capacity of the U.S., USSR, and British Empire. Better electronics might delay the outcome by 6-12 months but doesn't change it.
Pacific: The U.S. still wins, but the path might be different. Without the intelligence advantage from broken Japanese codes, more costly conventional operations might be needed. The atomic bomb, available slightly earlier, becomes even more decisive.
Casualties: This is genuinely uncertain. Better communications and radar on both sides might reduce some casualties (better warning, better coordination) while better weapons might increase others. I'd guess the war is slightly shorter in Europe but with similar total casualties, and slightly longer in the Pacific with higher Allied casualties.
By 1945 in this alternate timeline, transistor-based computers have been under development for 10-15 years. The wartime computing programs (equivalent to Bletchley's Colossus) would have produced a generation of engineers who understood digital computing deeply.
Key difference from our timeline: In our timeline, the transition from vacuum tubes to transistors in computing took roughly 1955-1965. In this timeline, that transition never happens — computers are transistor-based from the beginning.
What this means for computing development:
By 1950 (alternate timeline), the equivalent of our 1965 computing technology is plausible:
IBM's position: IBM in our timeline made the crucial transition from punch-card machines to electronic computers in the early 1950s, then from vacuum tubes to transistors in the late 1950s. In this timeline, IBM (or its equivalent) would be selling transistor-based business computers by the late 1940s.
Who benefits economically?
The United States, almost certainly, but with important caveats:
The Cold War's causes were geopolitical and ideological, not technological. The Soviet Union's emergence as a superpower, the division of Europe, the Chinese Revolution — none of these are altered by transistor technology.
However, the Cold War's conduct changes significantly.
Soviet computing: In our timeline, Soviet computing lagged badly. The USSR had excellent mathematicians but poor semiconductor manufacturing. In this alternate timeline, with transistors developed since the 1930s, the Soviets would have invested in semiconductor manufacturing during the industrialization drives of the late 1930s and the war. By 1950, Soviet computing might be only 5-7 years behind the U.S. rather than 15-20 years.
Intelligence and surveillance: Earlier computing means earlier signals intelligence capabilities. The NSA (founded 1952 in our timeline) equivalent would be processing more traffic earlier. Both superpowers would develop surveillance capabilities earlier.
Nuclear weapons: The arms race proceeds similarly. The Soviets tested their first atomic bomb in 1949 (our timeline) — with better computing, this might be 1947-1948. The hydrogen bomb race proceeds similarly but perhaps 2-3 years faster on both sides.
The "missile gap" politics: In our timeline, Sputnik (1957) shocked the American public and triggered massive investment in science education and aerospace. With earlier computing, rocket guidance systems would be more sophisticated earlier, potentially advancing the missile program on both sides.
United States: The postwar economic boom in our timeline was driven partly by pent-up consumer demand, the GI Bill, and new industries (television, automobiles, suburbanization). In this alternate timeline:
This last point has significant social implications I'll return to.
United Kingdom: Britain's postwar economic decline is one of the great puzzles of economic history. In our timeline, Britain had strong early computing (Ferranti Mark 1, LEO computer) but failed to commercialize it effectively.
With an earlier start, Britain's position is ambiguous:
Germany and Japan: Both were devastated by the war. In our timeline, both recovered dramatically partly by adopting the latest American technology.
With earlier transistor development:
With transistors available since the 1930s, and Japan having had a pre-war electronics industry, the post-war reconstruction would include electronics as a priority sector. Japan might reach its electronics export dominance 10-15 years earlier — by the mid-1960s rather than the late 1970s-1980s.
The space race in our timeline was fundamentally enabled by two things: rockets (V-2 technology, adapted by both superpowers) and electronics (guidance, telemetry, communication). The electronics were the binding constraint for early reliability.
With more advanced transistor electronics by 1955:
When does Sputnik happen?
In our timeline: October 4, 1957.
In this alternate timeline, with better electronics and a computing head start, the Soviets might achieve orbit by 1954-1955. The Americans, similarly advanced, might achieve it by 1953-1954.
The political dynamics of an earlier space race:
The shock of Sputnik in our timeline was partly because it was unexpected — the American public didn't know the Soviets were close. If the space race begins earlier, it might be more openly competitive from the start, with less of the surprise factor.
The Moon landing:
In our timeline, Apollo 11 landed July 20, 1969. The program required:
With better electronics available earlier, the technical barriers are lower. But the political will is the binding constraint, not the technology. Kennedy's commitment was a response to Soviet space achievements and Cold War competition.
Plausible scenario: The Moon landing happens by 1963-1965 in this alternate timeline — perhaps 5-6 years earlier. This is significant but not transformative for the broader geopolitical picture.
More important than the Moon: Earlier satellite technology means:
The reconnaissance satellite implication is particularly important: the U-2 incident (1960) might never happen because satellite reconnaissance would be available earlier, reducing the need for manned overflight missions. This removes one significant source of Cold War tension.
In our timeline, the transistor radio (Sony TR-55, 1955; Regency TR-1, 1954) democratized radio in the developing world. Cheap, battery-powered radios brought news and culture to populations without electrical infrastructure.
In this alternate timeline, this effect begins in the late 1940s. The social implications:
Decolonization: The post-WWII wave of decolonization (India 1947, African independence movements 1950s-1960s) was partly enabled by communications — nationalist movements could coordinate and spread their message. Earlier cheap radios might accelerate this process.
The developing world: Countries that in our timeline were "radio deserts" would be connected earlier. This has ambiguous effects — it could accelerate modernization and political mobilization, or it could accelerate the spread of propaganda.
American culture: The transistor radio in our timeline was closely associated with youth culture, rock and roll, and the social changes of the late 1950s-1960s. With portable radios available in the late 1940s, the cultural revolution might begin earlier — potentially a 1950s equivalent of the 1960s counterculture, happening in the late 1940s-early 1950s.
Television development was not primarily limited by transistors — it required CRT technology, broadcast standards, and infrastructure investment. However, transistors would make TVs cheaper, more reliable, and eventually smaller.
Our timeline: TV becomes mass market in the U.S. around 1950-1955.
Alternate timeline: TV becomes mass market around 1947-1950 — only slightly earlier, because the other constraints still apply. However, the sets are cheaper and more reliable from the beginning.
Color TV: In our timeline, color TV was a long battle (1950s-1960s) partly because of the electronic complexity. With better transistors earlier, color TV might be mass market by 1955 rather than the late 1960s.
This is where the most profound social changes occur.
In our timeline, business computing began in the late 1950s and transformed office work over the following decades. The IBM System/360 (1964) was the watershed moment for commercial computing.
In this alternate timeline, the equivalent of the System/360 arrives by 1952-1955. Business computing is widespread by 1960.
Labor market implications:
The postwar period in our timeline saw enormous growth in clerical employment — bookkeepers, typists, filing clerks, telephone operators. This was a major source of employment for women entering the workforce.
With earlier computing:
The "computer programmer" as a profession:
In our timeline, programming was initially women's work (ENIAC programmers, COBOL's Grace Hopper). As computing became more prestigious and lucrative, it became male-dominated.
With computing developing earlier and in a different social context (1940s-1950s rather than 1960s-1970s), the gender dynamics of the profession might be different. This is genuinely uncertain.
By 1980 in this alternate timeline, the U.S. economy would be approximately 15-20 years ahead of our timeline in information technology. What does that mean?
What would exist by 1980 (alternate) that didn't exist until later in our timeline:
But: The social adoption of technology doesn't automatically accelerate with the technology. The conceptual frameworks, business models, and cultural practices that allow technology to be used effectively develop at their own pace. The PC revolution in our timeline required not just the hardware but VisiCalc, word processing, the concept of the "personal" computer. These conceptual developments might not accelerate as fast as the hardware.
My estimate: By 1980 in the alternate timeline, U.S. information technology is roughly equivalent to our 1990-1995 — significantly ahead, but not as far ahead as the raw 27-year head start might suggest.
The U.S. economy by 1980 (alternate):
Japan's economic trajectory is one of the most interesting divergences.
In our timeline, Japan's electronics export success began in the 1960s (transistor radios, then televisions) and peaked in the 1980s (consumer electronics, semiconductors).
In this alternate timeline:
The "Japan problem" for the U.S. arrives earlier: In our timeline, American industries (steel, automobiles, consumer electronics) faced Japanese competition primarily in the 1970s-1980s. In this alternate timeline, the consumer electronics competition arrives in the 1960s. This might actually be better for the U.S. long-term — the disruption comes when the U.S. economy is stronger and more adaptable.
The European Economic Community (1957 in our timeline) would form on a similar schedule — it's driven by political factors, not technology. However, European technology firms would be more competitive:
The "technology gap" debate: In the 1960s, our timeline saw significant concern in Europe about American dominance of computing (Jean-Jacques Servan-Schreiber's "The American Challenge," 1967). This debate would happen earlier and might produce different policy responses.
The Soviet economy by 1980 in this alternate timeline is genuinely uncertain.
Arguments for a stronger Soviet position:
Arguments against:
My assessment: The Soviet Union by 1980 (alternate) is more technologically sophisticated in military and space applications, but the civilian economy is not dramatically better. The systemic problems of Soviet planning are not computational — they're about incentives and information that computers alone can't fix.
Important: Mikhail Gorbachev's reforms (our timeline: 1985-1991) were partly motivated by the Soviet economy falling behind technologically. With a smaller technology gap, the pressure for reform might be less. The Soviet Union might survive longer in this alternate timeline — potentially into the 1990s or beyond. This is a significant geopolitical divergence.
Earlier automation creates a paradox: productivity gains arrive before the social and institutional frameworks to manage them.
In our timeline, the transition from manufacturing to service employment happened over decades, with significant social disruption but also adaptation. With earlier automation:
The 1950s might see significant unemployment as clerical and manufacturing jobs are automated faster than new sectors emerge. This could produce:
The irony: Earlier transistors might produce a more interventionist government in the 1950s-1960s, as the social disruption of automation requires policy responses.
Earlier computing means earlier development of complex financial instruments.
In our timeline, the financial innovations that led to the 2008 crisis (mortgage-backed securities, CDOs, credit default swaps) required computing power that wasn't available until the 1990s-2000s.
In this alternate timeline, similar financial innovations might appear in the 1960s-1970s. With less regulatory experience and less sophisticated risk management, a major financial crisis similar to 2008 might occur in the 1975-1985 timeframe.
This is a genuinely underappreciated consequence: Earlier computing doesn't just mean earlier benefits — it means earlier versions of computing-enabled disasters.
Earlier computing means earlier capability for mass surveillance.
In our timeline, the NSA's mass surveillance capabilities (PRISM, etc., revealed by Snowden in 2013) required decades of computing development. In this alternate timeline, similar capabilities might exist by the 1970s.
The political implications depend on which governments have these capabilities and what the legal/cultural constraints are. In the Cold War context, both superpowers would develop mass surveillance capabilities, but so would authoritarian governments worldwide.
Could this help authoritarian regimes survive longer? Possibly. The Stasi (East German secret police) in our timeline was limited by the physical impossibility of processing all the information they collected. With earlier computing, digital surveillance of dissidents becomes more effective. This might mean:
Earlier industrialization of electronics means earlier environmental consequences.
In our timeline, the environmental problems of semiconductor manufacturing (toxic chemicals, heavy metal contamination) became apparent in Silicon Valley in the 1980s. With earlier development:
More broadly: Earlier productivity growth means earlier increases in consumption and resource use. The environmental pressures of our late 20th century might arrive in the 1960s-1970s in this alternate timeline.
Earlier computing accelerates medical research in specific ways:
A plausible scenario: The AIDS epidemic (our timeline: identified 1981) might be identified and its cause determined faster with better computing and biological research tools. Treatment might arrive by the mid-1980s rather than the late 1990s — potentially saving millions of lives.
United States: The U.S. benefits most, for the same reasons it benefited most in our timeline — large domestic market, strong capital markets, excellent universities, immigration of talent, and a corporate culture capable of commercializing technology. The lead is larger and longer in this timeline.
Japan: As discussed, Japan's electronics export success arrives earlier and is larger. Japan might be the world's second-largest economy by the late 1960s rather than 1968 (which is actually when it happened in our timeline — Japan surpassed West Germany in 1968). The difference is in the composition: Japan in this timeline would be more focused on electronics and computing, less on steel and heavy industry.
Israel: In our timeline, Israel developed a significant technology sector partly by attracting diaspora talent and partly through military technology requirements. With earlier computing, Israel's technology sector might develop in the 1960s rather than the 1990s-2000s. This would significantly change Israel's economic position and potentially its geopolitical leverage.
South Korea: In our timeline, South Korea's electronics industry (Samsung, LG) developed in the 1970s-1980s. With earlier technology available and the same developmental state model, Korean electronics might emerge in the 1960s.
Germany: Germany has strong pre-war electronics expertise but the war's devastation is a major setback. West Germany probably benefits significantly but the timing of recovery is uncertain.
India: India in our timeline has a significant software industry (developed from the 1990s). With earlier computing, India might develop this earlier — but the educational infrastructure and English-language advantage would need to develop first. The Indian Institutes of Technology (founded 1950s) would be producing computing graduates earlier.
China: The People's Republic was founded in 1949. Mao's China was deeply suspicious of technology (the Cultural Revolution 1966-1976 devastated Chinese science). Earlier transistors don't obviously help China until after Deng Xiaoping's reforms. China might be in a worse relative position by 1980 because the gap between China and the advanced economies would be larger.
Countries dependent on clerical employment: Countries that in our timeline developed significant clerical service sectors as a path to development would find that path partially closed by earlier automation.
Soviet bloc countries: The combination of earlier Western computing advantage and potentially more capable surveillance technology keeping authoritarian regimes in power would leave Soviet bloc populations worse off.
Countries with extractive resource economies: The productivity gains from computing would widen the gap between knowledge economies and resource economies faster. Oil-exporting countries would have the same oil revenues but face more technologically advanced trading partners.
| Domain | Our Timeline (1980) | Alternate Timeline (1980) |
|---|---|---|
| Computing | Mainframes dominant, PCs emerging | PCs widespread, early internet |
| Communications | Analog telephone, early satellite | Digital communications widespread |
| Space | Shuttle era beginning | Permanent space station plausible |
| Cold War | USSR declining but intact | USSR more stable, smaller tech gap |
| Japan | Electronics export surge | Already dominant, 15 years ahead |
| Financial markets | Early computerization | Complex instruments, possible crisis |
| Surveillance | Limited state surveillance | Mass digital surveillance operational |
| Medicine | Early CT, no HIV treatment | Better imaging, faster drug development |
| Environment | Environmental movement established | Earlier environmental pressure |
I want to flag where I'm least confident:
The pace of diffusion: I've assumed technology diffuses at roughly historical rates. But earlier transistors might change the institutions that diffuse technology, making diffusion faster or slower in ways that are hard to predict.
Soviet trajectory: The Soviet Union is the hardest case. The range of plausible outcomes is wide — from collapse in the 1970s (if the technology gap is larger) to survival into the 2000s (if better surveillance and military technology maintains the regime).
Social adaptation: I've assumed societies adapt to technology at roughly historical rates. But earlier disruption might produce earlier adaptation — or earlier backlash. The political economy of automation is genuinely uncertain.
Second-order innovation: Earlier computing would change what problems researchers work on. Some innovations in our timeline (certain drugs, certain materials) were discovered partly by accident or through computational methods. In this alternate timeline, different things would be discovered, not just the same things earlier. I've largely ignored this because it's too speculative to trace.
The counterfactual's internal consistency: Any 27-year technology shift creates cascading changes that eventually become impossible to trace. By 1980, the alternate timeline is so different that specific predictions become increasingly unreliable.
The most important thing about this exercise is what it reveals about technological change generally:
Technology is necessary but not sufficient. The transistor didn't determine outcomes — it changed the costs and capabilities available to actors who were pursuing their own goals for their own reasons. Wars happen because of politics, not technology. Economies grow because of institutions and incentives, not just tools. Social change follows its own logic.
An earlier transistor would have made many things possible sooner. It would not have made humans wiser, more cooperative, or less prone to the errors that actually shaped the 20th century. The same technologies that enable communication enable surveillance. The same computing that enables medicine enables weapons. The same productivity that creates wealth creates disruption.
The 27-year head start would matter enormously in specific domains (computing, communications, space). It would matter much less in others (war, political economy, human nature). And it would create new problems — financial instability, earlier automation disruption, earlier surveillance capabilities — that we haven't solved even in our own timeline.
