The idea that somehow the law of conservation of energy applies to the security of block chains, or computing in general. The fact that tweets 1-20 come from a cryptocurrency developer is terrifying, because it reads like a speculator trying to drive down Ethereum. I get what the developer is trying to say, but it all falls apart once they tie "electricity expended in Proof of X directly maps to amount of ledger security". Tweets 21+ are actually reasonable and well thought out. It's that whole nonsense in the first 20 that just poisons the whole thread. I completely agree that PoS assumes that bad actors are at best a group of Chaotic Evil backstabbers and that there'd never be a massive organization of Lawful Evil people rewriting the block chain. Furthermore, it doesn't account for a group of possibly Chaotic Good miners "correcting" a coin heist by rewriting the block chain. It is the stance of a majority of cryptocurrency participants that such a power is corrupting and that no matter what, the block chain must stand immutable.
