I think it's actually likelier that you could convince JD Vance to pull a Ser Jaime Lannister than to invoke the 25A

All you have to do is go "There's a buffer overflow in strtok.c line [predict]"

These things just predict the next token. Nothing to worry about.

A line graph of four emotions (desperate, hopeful, satisfied, obstinate) over token count during an AI task. The lines move erratically, ending on high confidence and low desperation

I used to live near a meat processing facility; when the wind shifted you would just soak in the stench of death all day.

Now I live near a data interchange building instead, which you wouldn't really know if it didn't have a small sign on the door.

Seems like the 25th Amendment may have been a mistake, since it creates the "No YOU get rid of him" dynamic that we're seeing today.

Just change the impeachment clause to "high crimes, misdemeanors, or incapacitation" instead

You can tell this comic wasn't AI-generated because it has correctly-drawn text and hands, two things AI cannot and will not ever be able to do

This isn't economical today because you need a human to do all the records-digging to find good targets. It's pennies to do this with a AI.

Am I going to pay a convenient $38 bill from Olympia Dental Subservices for my appointment last week, correctly-dated and correctly-addressed? Probably!

Free idea to keep you up at night: bot that sits on social media feeds looking for people mentioning going to the dentist, mines info from public records to find their address, prints out a plausible-looking bill with a QR code to pay with Stripe.

Do you ever even get caught doing this?

Just please think adversarially for one full minute about what you could do right now with a few hundred dollars of tokens. If you're not at least a little bit panicked, you're not thinking hard enough, or have deluded yourself about what's possible.

A three-panel comic strip, drawn with a rough colored pencil style

First panel: We see a door in a hallway, it's slightly ajar. The sign on the door says "Robot Detection Lab"

Second panel: A man resembling a young Harrison Ford holds a clipboard. He faces to our right. We see him from the side. He looks like he's thinking very hard, his brow is furrowed. He holds a clipboard, and we can see on the clipboard that there many line items on it with both checkmarks and x's next to them, indicating he's received mixed responses. A speech bubble from him says "What might you say after fixing a bug?" The most obvious robot you've ever seen in your life, facing to our left, is wearing an orange baseball cap that says "Human!". It leans back casually in the chair, smiling, as if to exude humanness. The speech bubble from the robot says "All 418 regex-related tests pass".

Third panel: We see a zoom-in on the clipboard, with the hand visible, writing "Inconclusive" on the bottom of the page

I don't care that your PR is vibecoded but it's weird that you're neither telling me nor trying to hide it

Every time you watch a baseball game you might see something that's never happened before (derogatory)

One of the worst defenders in baseball just did a thing no defender has ever done before, so that that Mariners couldn't even tie it up. Just the usual.

Likely the first time ever a player has robbed 3 HRs in a single game? And to hold a 1-0 lead. A literal +1 WAR performance. Unreal.

If too many people name their kids in a way that defies racial expectations, then employers and landlords won't be able to secretly screen for race, which is uhhhh bad I guess?

good animation! I've always thought a good jiu-jitsu comms idea for a Dem candidate would be to *propose* marginal taxation — call it "The [Candidate Name] Plan" and patiently explain.

If media wants to step in and challenge you by explaining it already works like that... mission accomplished.

If you call yourself a writer you definitionally should not be using an LLM to produce text to give to someone else.

On the other hand if you are this person, maybe consider it:
