In college on my way to class I would pick random flowers around campus and eat them. My bio prof told me this was ill advised. I continued eating the flowers.

All of o3's results here actually depict empires negatively. Yuval Noah Harari in Sapiens asks the forbidden question, "Are people actually happier in empires?"

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers. The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

Difficulty with lean:.One can have an intuition of a proof and high certainty it's correct without lean. One can have a valid lean proof and absolutely no intuition about it. @ChrSzegedy is the future of math lambda calculus proofs we derive no intuition from?.

.@dwarkesh_sp: "All of the data available in 1980 would be nowhere near enough to train GPT4.".Suppose letting loose the AI too early stymies the ability to develop transformative AI. The data sources (the Internet) become full of AI slop and we miss out on orders of magnitude.

Moscone Center, Howard & 3rd. A (probably homeless) man walking across street against traffic, no walk sign. I stop to let him pass. He starts jerking off in front of my car, spits on my car, and then lunges at my mirror. We have insane, violent people all around us, when did we

Elio: The voices of Carl Sagan and Captain Janeway were a nice touch. The Phoenician Scheme: I fell asleep. :|. 28 Years Later: Boots, boots, boots. Phenomenal. Rudyard Kipling, Teletubbies, and Sycamore Gap were nice touches. Shot on iPhone.

Humanoid robots are very far from replacing human caregivers for babies and toddlers. There is an enormous amount of information transferred in both facial expressions and smell that robots are very far from achieving. Not to mention a vital transfer of (good) bacteria.

Equinox Sauna Four Seasons SF: ."Our company mandated 90% of code must be written by AI.".Now I realize why coding agents are so insanely verbose. We're Goodhart's Law-ing lines of code. Writing 100 LOC to do what 5 would've sufficed is a feature. Hit those enterprise metrics.
