Is there another US governmental organization that you think would be better suited? My relatively uninformed sense is that there's no real USFG organization that would be very well-suited for this—and given that NIST is probably one of the better choices.

Summarizing from the private conversation: the information there is not new to me and I don't think your description of what they said is accurate.

As I've said previously, Anthropic people certainly went around saying things like "we want to think carefully about when to do releases and try to advance capabilities for the purpose of doing safety", but it was always extremely clear at least to me that these were not commitments, just general thoughts about strategy, and I am very confident that was what was being referred to as being widespread in 2022 here.

I think it was an honest miscommunication coupled to a game of telephone—the sort of thing that inevitably happens sometimes—but not something that I feel particularly concerned about.

I mostly believe y'all about 2—I didn't know 2 until people asserted it right after the Claude 3 release, but I haven't been around the community, much less well-connected in it, for long—but that feels like an honest miscommunication to me.

For the record, I have been around the community for a long time (since before Anthropic existed), in a very involved way, and I had also basically never heard of this before the Claude 3 release. I can recall only one time where I ever heard someone mention something like this, it was a non-Anthropic person who said they heard it from someone else who was a non-Anthropic person, they asked me if I had heard the same thing, and I said no. So it certainly seems clear given all the reports that this was a real rumour that was going around, but it was definitely not the case that this was just an obvious thing that everyone in the community knew about or that Anthropic senior staff were regularly saying (I talked regularly to a lot of Anthropic senior staff before I joined Anthropic and I never heard anyone say this).

Pilot wave theory keeps all of standard wave mechanics unchanged, but then adds on top rules for how the wave "pushes around" classical particles. But it never zeroes out parts of the wave—the entirety of wave mechanics, including the full superposition and all the multiple worlds that implies, are still necessary to compute the exact structure of that wave to understand how it will push around the classical particles. Pilot wave theory then just declares that everything other than the classical particles "don't exist", which doesn't really make sense because the multiple worlds still have to exist in some sense because you have to compute them to understand how the wave will push around the classical particles.

See my discussion of pilot wave theory here.
