Vitalik is a man, not a god.

As long as you look at it from this perspective, everything is clear. I really like the analogy in the article "On the Impact of Vitalik and Various Roadmaps on Ethereum Governance Process" compiled by Geek Web3, that is, Vitalik actually plays a substantive "CTO" role in the Ethereum ecosystem to control the giant ship of Ethereum from deviating from the track:

Responsible for guiding the development process of Ethereum to be consistent with the planning direction of each "roadmap", and even has the final say on whether the development direction is in line with the vision of Ethereum (regardless of whether he is willing to be so "dictatorial")~
