Vitalik was a big blocks supporter for a long time. I saw this post as a 180 as well.
"Now I personally can see that it’s not axiomatically true that doing nothing is safest, especially in the context of a changing environment (for example I continue to believe that Bitcoin’s failure to raise its blocksize by a significant amount in 2016–17 was a travesty and a great violation of many people’s expectations of the protocol, and one that led to more total losses due to excess txfees than the amount lost in the MtGox hack), but this is the argument that you need to be arguing against."[1]
It's literally the only comments on Ethereum there have been from knowledgeable people. Show me a source from an expert that thinks Ethereum would scale
All the experts, including the numerous researchers who work on and have contributed to ETH 2.0, say Ethereum can scale. Any one with a passing familiarity with the cryptocurrency space knows that.
The only people who claim Ethereum can't scale are those who claim Lightning Network can scale, and have aggressively silenced any one who says otherwise within the Bitcoin space for the last six years, while declaring themselves to be the only experts on the issue.
Who cares who claims what? It's more important to hear the reasons behind the claims. Vitalik makes excellent points about tolerances and safety margins needed in decentralized networks like this. People who call for increasing the key parameters almost never acknowledge the fact that things aren't as simple as what some fast machines can process in ideal conditions.
