      1/ Here’s why I think Ethereum & Proof-of-Stake are bad ideas.

      2/ Bitcoin ledger (relative) immutability isn’t magic, it has that special property only because it pays an extremely high price for it. That price is PoW mining.

      3/ PoS proponents claim they can achieve the same immutability property, while doing away with this “wasteful” mining and as a result, operate at a fraction of the cost.

      4/ There’s something very similar to PoS in the history of technology, it’s called the idea of a Perpetual Motion Machine.

      5/ In the 19th & 20th centuries, people spent tons of money & effort trying to create a Perpetual Motion Machine. A Perpetual Motion Machine produces perpetual motion without requiring any energy, essentially creating energy out of thin air.

      6/ Similarly, PoS promises ledger immutability without requiring any upfront cost, basically creating ledger security out of thin air.

      Your argument is flawed because of a bad analogy. Every day engineers work out ways to get more performance out of less power. Proof of stake doesn’t use no energy - it uses less energy to achieve a similar result. Hardly a perpetual motion machine. Nice straw-man though 😜.

      That’s different because in those cases there are exploitable inefficiencies, whereas every hash in PoW goes to secure the ledger. One hash mined == one hash harder to revert.

          The work in PoW comes from searching the hash space (mining) not from creating an individual hash. Immutability comes from an honest majority sharing the same history. PoS improves the inefficiency (mining) while achieving a similar result (honest majority with same history).

          "similar result" is your quite arguable conclusion. The "honest majority" of machine consensus is more provably true than consensus involving corruptible humans.

          Who said anything about human consensus? In both PoS and PoW the majority of nodes (machines) share the same history (consensus). If they don’t you have orphans or a hard fork. Human consensus has nothing to do with PoS. Another straw man argument...

          You are conflating the generation of the history with the history itself. Your claim is basically that the only way to securely get that history is through mining. If that were true every new node would need to re-mine everything.
