I think most of HN can't logically arrive at this conclusion because they don't exactly buy into the premise that

(1) (digital) AGI is a real concept, and will be achieved imminently

(2) AGI will be world (and possibly more) changing.

(3) Anthropic will be the one to do that, or at least capture a large part of it

If you buy into all of these, which I'm assuming a lot of SV does at this point, then its kind of a no brainer to go to OpenAI or Anthropic. And optics wise it seems like Anthropic is "winning" right now, so thats the lab with the talent flow.

If Anthropic actually creates a singleton, contributing to that is way more impactful than being CTO at some random company (though I may disagree that said singleton would treat equity holders any differently).
