For anyone who might be concerned by the claim here; it’s really a political argument and not a technical one. Proof of stake as implemented by Ethereum makes a tradeoff which requires some small amount of trust (to identify the correct chain more quickly) which does not create a centralization risk. But this is always the way; leveraging trust where appropriate can allow great increases in efficiency, this is how society works, so you have a political spectrum where Ethereum is “responsibly pro social” and Bitcoin is still a kind of super trust less money with enormous energy costs to enable this somewhat superficial security property.
