Precisely said.
> It seems like some people, just because they are smart in one area, think they know everything. We see this with many VCs, Elon Musk, Vitalik etc.
Totally correct. Elon's wild claims on solving FSD (Fools Self Driving) seemed to be a total disaster, and Vitalik's claims on his decentralized slot machine utopia 'Ethereum' on how using a generalized blockchain to solve 'anything' from voting, social networks, DAOs, NFTs, etc has manifested into a tinkerbell griftopia [0] as feared by even the most fierce critics of blockchains.
Finally, VCs really don't care on being wrong on thousands of failed investments. They just need one massive return to make up for all of it hundreds of times over and somehow they are viewed as 'experts' which is a great example of the Texas sharpshooter fallacy. We don't hear them screaming about Clubhouse which was hyped to the extreme since it is isn't doing great as expected after being copied to death.
Also reading this article in particular, it is gearing close to sophistry.
