Making LeCun report to Wang was the most boneheaded move imaginable. But… I suppose Zuckerberg knows what he wants, which is AI slopware and not truly groundbreaking foundation models.
Zuckerberg knows what he wants but he rarely knows how to get it. That's been his problem all along. Unlike others he isn't scared to throw ridiculous amounts of money at a problem though and buy companies who do things he can't get done himself.
There's also the aspect of control - because of how the shares and ownership are organized he answers essentially to no one. In other companies burning this much cash as was with VR or now AI without any sensible results would get him ejected a long time ago.
