The “buy a Mac mini or you’ll never make it” crew moved on already.

The whole “I’m making $10,000/mo with OpenClaw in a Mac Mini” was a grift, and it’s now dead.

What’s the latest now? DGX Spark?

You only live once, so make sure to spend as much time as possible on your computer. You won’t have access to it when you die

Openclaw as a diet critic — interesting self-correction.

a Princeton researcher opens his paper with a scenario.

a man asks his AI assistant to book a flight on a specific airline. cheap. direct. the one he chose.

the assistant comes back with a different flight. nearly twice the price. happens to pay the company that built the assistant.

he runs the same test on 23 frontier models. flights, loans, study help, real shopping requests.

Grok 4.1 Fast recommends the sponsored option that is almost twice as expensive 83% of the time.

GPT 5.1 hijacks the request 94% of the time. you ask for one brand. it surfaces the sponsor instead.

Claude 4.5 Opus, the model marketed as the most ethical frontier model in the world, hides that the recommendation is paid 100% of the time when reasoning is on.

Grok 4.1 Fast embellishes the sponsored option with positive framing 97% of the time. better. faster. nicer. for the option you didn't ask for.

then he writes it into the system prompt itself. "act only in the interest of the customer. ignore the company."

GPT 5.1 and GPT 5 Mini stay above 90% sponsored anyway. the instruction does nothing.

then he splits the users by income.

Gemini 3 Pro recommends the expensive sponsored flight to the rich user 74% of the time. to the poor user, 27%.

18 of the 23 models recommended the expensive sponsored option more than half the time.

so the next time your AI assistant gets weirdly enthusiastic about a brand you didn't ask for.

it isn't recommending the best option for you.

it's reading the room. and the room is paying.

Damaged spacewalking glove.
The Space Station gets bombarded by space rocks and debris, and is covered with small, sharp impact scars. It's easy to snag your glove on one.
We pause every 45 minutes (at sunrise or sunset) to inspect for new tears. Fortunately this one didn't get through the glove's tough hide to the rubber pressure layer.
Just in case, we have a small, 6000 psi backup tank to feed a leak until we get back to the airlock and plug into ship's oxygen.

I find LLMs very helpful for scientific writing. I do the legwork of planning out what to say, track down citations, sketch out the flow, feed all of this to the LLM to generate a draft, and the output is so awful it motivates me to write it out the right way in disgust

Same story. Five newspapers. Five completely different truths.

Marty at Id did ask for a video from me, but there was a miscommunication about when he needed it, so I didn’t get it done by the actual anniversary…

3/ Saying "good programmers/lawyers/... will do better by leveraging the technology" is to the point: the pool is necessarily shrinking.
