Something surprising Sam Altman mentioned on the Lex Fridman podcast was that it only takes about 6 months to get a top physicist up to speed and productive researching AI. So the team could largely be newbies to AI (with extremely good fundamental knowledge/skill), rather than folks we've all heard of from the AI scene.
There is nothing really surprising about this. Jim Simmons that recently passed away did exactly this in finance decades ago. He didn't build a team of the brightest minds in finance. He hired brilliant people that specifically did not work in finance. I think he even mentioned that astronomy was one of his favorite areas to hire from for finance. I am sure we highly underestimate the indoctrination against new ideas…
I suppose I shouldn't be surprised that AI development appears to be heading the same way.
