The claim that most domains are shallow enough for a generalist to get going quickly does not apply to every domain.

“sort of train and talk to people and show up their expertise and do some practice they would actually do like a pretty good job i think most domains are fundamentally pretty shallow where like a very smart generalist who's good at like a limited subset of core skills can like get going pretty quickly um and my sense is that like that's not true for literally every domain and my sense is that the ais will develop increasingly good mechanisms for quickly acquiring understanding and expertise in a given domain”
