It's a step up from the "crypto isn't crypto" mantra that many used to repeat, refusing to even look at how it works. Not sure why it took something as silly as art NFTs, but it does seem that now even those who previously tried avoiding cryptocurrencies at all cost have at least started looking at them critically. He does point out some real problems. Yes, all this has been discussed in the Ethereum community already and many in the community have voiced the same criticisms as well. But a lot of the issues are still unsolved for regular mainstream users, who rely on a lot of centralized services and are often herded into solutions that may bring more convenience but are also less secure. It's good we're having discussions about this, and the more people that point out flaws the better. After all the entire point of a blockchain is to be public and robust. If this is our future money or notary service, the more probing the better.
