Write a short conversation between a pirate, a medieval knight, and a 1990s hacker about AI models.

Pirate: Arrr, so this “AI model” be like a clever parrot, aye? Learns from what it hears, then squawks back answers?

Knight: A fair comparison, though refined. Think of it as a squire trained on countless tomes, ever ready to respond.

Hacker (1990s): Yeah, except the squire runs on servers, not soup. Feed it data, tune the weights, boom—pattern machine.

Pirate: Can it chart a course through storm and cannon fire?

Hacker (1990s): If it’s seen enough weather and battle logs, it can predict stuff. Doesn’t understand like a human, though.

Knight: So it has knowledge, yet no wisdom.

Pirate: Like me first mate, then.

Hacker (1990s): Exactly. Also, garbage in, garbage out. Bad data makes dumb AI.

Knight: Then we must train it with honest records, lest it become a most confident fool.

Pirate: Har! A metal deckhand with attitude. I’ll take two.
