I watched Jihan's talk.  I think you're missing the subtext here. Jihan doesn't like the Core team's committee approach. He would rather have a benevolent dictator leading the team, who could take decisive action. This is in line with the political environment of China right now.

I do tend to agree that committee leadership can easily get stalled. But benevolent dictatorship is not immune to problems either.

We'll see whether Jihan or one of his allies can come up with a better project led by a stronger leader for Bitcoin than Core has so far.
