Right now, what seems to be missing from general intelligence is mostly the ability to learn from experience and continue operating in a useful way well beyond context window size. That might already be technically feasible, but probably not in a cost-effective way.
I have no idea. Anyone claiming to is hubristic.
What I mean by Occam's Razor:
There are many assumptions that need to be true to link "they say they're terrified of AI" to "they get paid more / longer", in both their own minds and everyone else's. It's a bit of 4D chess that could go their way, but also could go 100 different ways.
In contrast, linking "they say it" to "they believe it" is simple.
