So I've been using those AI assistants a lot lately, and I realized something terrifying. The AI knows me better than I know myself.
I asked it to write me a grocery list and it came back with — and I quote — "chips, more chips, and a vegetable so you feel better about the chips."
That's not a grocery list. That's a psychological profile.
I tried to get healthy recently. I downloaded one of those fitness apps that tracks everything. Steps, calories, sleep, heart rate. Everything.
Day one, I'm feeling motivated. I go for a walk. The app says, "Great job! You've completed four percent of your daily goal."
Four percent.
I walked to my mailbox and back. The app looked at that and essentially said, "Buddy, we need to talk."
The sleep tracking is the worst part. I wake up and the app tells me how I slept. Like I need a second opinion on that.
I KNOW how I slept. I was there.
"You spent forty minutes in deep sleep and six hours just sort of... existing." Yeah. That's called being an adult. We don't sleep anymore. We just lie down and worry horizontally.
My phone now interrupts me to tell me I've been on my phone too long.
Think about that. The phone is concerned about me. The phone has drawn a boundary.
I've been in relationships that never reached that level of self-awareness.
"Screen time is up thirty percent this week." Okay but in my defense, I was reading. "You were watching a man fall off a skateboard for two hours." ...It was the same man. I got invested.
I tried meditation to deal with the stress. Downloaded a meditation app — because apparently the cure for too much phone is more phone.
The app has this calming voice that says, "Clear your mind of all thoughts."
And my brain goes, "Okay. No thoughts."
Two seconds later: "Did I leave the stove on? What IS a mortgage, really? Why do they call it a building if it's already built?"
The app says, "You're doing great."
It's lying. The app is lying to me and somehow that's the most comforting thing anyone has said to me all week.
I think that's the thing about modern life. We've built all this technology to make us feel better, and mostly what it does is hold up a very precise, data-driven mirror and go, "Look at yourself."
And we look.
And we go back to the chips.
Thank you, you've been wonderful.

[Comedian walks onstage]
Hey, everyone! Great to see you all tonight. I'm Jamie—if you thought that intro was enthusiastic, you should've seen me when I realized this place has Wi-Fi.
Seriously, though, I love stand-up. For one thing, I get to share all the weird stuff I secretly do in my apartment… and instead of calling the cops, you guys just laugh. That's high-quality entertainment right there.
So, the other day I'm in the self-checkout lane at the grocery store—because I'm the kind of person who's thrilled by the thought of scanning my own kale. Of course, there's always that one person holding up everyone behind them because they can't figure out how to scan a cucumber. Meanwhile, the machine flashes: "UNEXPECTED ITEM IN BAGGING AREA." It's staring at me like it's personally offended that I tried to buy almonds in instead of potato chips. I'm over here trying to reason with it:
"Look, buddy, I'm just trying to eat slightly healthier. Isn't that what we all want?"
Then it asks me, "Do you want a produce discount?" The only discount I want is one that lets me leave this line five minutes ago. I press "No," and the machine glares at me with a red light and calls for help like I'm smuggling avocados under my shirt.
My phone has ruined me. I can't have any thought longer than three seconds without Instagram interrupting me. I'll be in the shower—fresh shampoo, head full of suds—and in my brain:
"Did my neighbor's cat post another selfie? I need to check."
Fifteen minutes later I'm drying off, scrolling through cats wearing sweaters. Why are cats always more photogenic than me? They don't even try. They're just like, "You feed me, you click 'Like.'" I wish I could have a boundary like that—"Hey, you gave me pizza once; you can go ahead and like my vacation photos."
Anyone here stuck in a group chat you can't escape? There's always that one friend who forwards the exact same video one hundred times, and everybody else thinks it's the highlight of their week. I just mute my phone like it's an ex sending memes at 2 a.m. Then I wake up at dawn, bleary-eyed, thinking, "What did I miss?" I open my phone—and it's Bob celebrating his new air-fryer chicken recipe for the fifth time. Meanwhile, I burned my eggs so badly this morning that my smoke alarm filed a restraining order against me.
I decided to get in shape. I downloaded one of those workout apps promising "six-pack abs in six weeks." After day one, I collected six new excuses why I can't work out:
Yesterday I finally ran so hard I passed out. When I came to, my neighbor was standing over me yelling, "You know you're not supposed to lean on lampposts, right?" I told him, "As soon as lampposts start offering aerodynamic support, I'll consider trusting them."
Alright, folks, that's my time. If you ever feel judged by a machine or betrayed by a group chat, come find me—I'll be the one in the self-checkout line, trying to convince a barcode scanner that kale is, in fact, a food. Thanks so much—you've been awesome!
