PoS == Consensus Failures (Score 1)

Every single PoS system I've participated in has had consensus problems. That means, the chain "froze" for a time before the issue could be resolved. Some people may put up with Solana going down for 8 hours at a stretch, but when the chain you depend on for everything else stops -- its a deal-breaker. If the ETH devs don't kick the can (again) and put off the "logic bomb", when they finally migrate they may find out that there is no such thing as a free lunch. Posting tokens as a validator is not equivalent to spending energy to secure a chain. You can tell this is true just by the mechanisms they have to employ on top -- a true "who watches the watchmen" scenario unfolds. Mark my words, they will have a consensus failure on the ETH PoS chain. ETH PoW may be the only thing that saves them from total oblivion.
