"The Algorithm Knows Me Too Well"

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.

3-Minute Stand-Up Comedy Routine

Opening: Hey everyone! How's it going? You know, I've been thinking a lot about relationships lately. Not because I'm in one, but because I'm not. And that's the problem. I'm single, and I'm starting to think that my dating profile is the reason why.

Dating Profile: I mean, have you ever tried to write a dating profile? It's like trying to sell a used car that's been in three accidents and has a weird smell. "Runs great! Just needs a little love." And the photos? I have to choose between looking like a serial killer or a guy who's trying too hard. "Here's me hiking! I don't actually hike, but I thought it would make me look adventurous."

First Dates: First dates are the worst. You're trying to be charming, but you're also trying not to be a creep. It's a fine line. Like, "Hey, you look nice tonight." That's fine. But if you say, "Hey, you look nice tonight... in that dress... that you're wearing... that I can see you in," suddenly you're on a watchlist.

Texting: And then there's texting. Why is it so hard to text someone you like? You spend 20 minutes crafting the perfect message, and then they reply with "K." "K"? What does that even mean? Are you mad? Are you busy? Are you a robot? Because if you are, I'm into it. At least robots respond.

Social Media: Social media doesn't help either. You see all these couples posting about their perfect lives. "Look at us on this beach! We're so in love!" Meanwhile, I'm at home eating cereal for dinner and watching Netflix. But you know what? I'm happy for them. Really. I'm just over here living my best life, one episode at a time.

Family Pressure: And then there's the family pressure. My mom is always asking, "When are you going to settle down?" Mom, I'm trying. But it's hard out here. It's like the Hunger Games, but instead of fighting to the death, we're swiping left and right. And sometimes, it feels like death would be easier.

Self-Improvement: I've tried self-improvement. I read a book on how to be more confident. It said, "Fake it till you make it." So, I walked into a bar and pretended to be James Bond. I ordered a martini, shaken, not stirred. The bartender said, "We don't serve martinis here." I said, "Well, this is awkward." He said, "No, this is a coffee shop."

Conclusion: But you know what? I'm not giving up. I'm going to keep trying. Because one day, I'll find someone who loves me for who I am. Someone who appreciates my weird sense of humor and my love for cereal. And until then, I'll be here, swiping right on robots and hoping for the best. Thanks, everyone!

Closing: Thanks for listening, you've been a great audience! Remember, if you're single, it's not you, it's them. And if you're in a relationship, well, good for you. I guess. No, I'm kidding. Love is great. I'm just bitter. Have a good night!
