My pronouns are nerd/geek. I hope I'm an ally to many and an enemy to few. I can't believe bsky ran out of more interesting people to invite.

That reminds me of a presentation I saw recently. The speaker's team ran the same #AI code eval tool with the same model over the same code multiple times. It found different things out to at least 10 runs, and run 10 found way more new stuff than runs 8 and 9. Nondeterminism gonna nondetermine?

Pro-tip: For personal interactions in my world, "yes" is not enough. "Yes" can occupy the middle ground between "don't want" and "want". Folks talk about "consent" as if it's synonymous with "desire". It's not. You either "want" something, or you don't. Period. That's my personal minimum.

As over the top as the movie was, it feels like the AI Bros are our home-grown Abrasax family from Jupiter Ascending, all doing Eddie Redmayne's "I give life!" speech at the tops of their lungs. Funny how they always seem to model themselves on the villains from sci-fi...

When Sam Altman first started talking about #AI needing trillions of dollars of infrastructure investment, I wrote him off as a crank. "We can't scrape up $2T for our roads and bridges! We can't even do high speed rail in this country!" Wow, do I feel like an idiot now... 🤦‍♂️

True, but a lot of things could influence that. Were they ever on the same network? Did they start as copies of the same code? Are they brute-forcing their way through every possible bit of the hardware they can control in order to communicate? 🤷‍♂️

It could be a very low bandwidth form of side-channel communication. Speaker/microphone. Display/camera. Infrared emitter/receiver. Smoke signals. Running the CPU fans at specific RPMs/microphones. You name it. It doesn't even have to be symmetric.

There seems to be some research on reducing contrails (no chem) in order to reduce the impact of travel, but the whole chemtrail thing is just ... bonkers. RFKjr is well past bonkers.

I'm iffy about some of the spec-driven coding stuff, but that's mighty close to putting the code *behind* the tool where the human can't get unfettered access. The tool can distill the codebase in a durable way because it can't be backdoored, and (re)builds solely from its internal representation.
