General mathematics and computer science don't require burning energy on the scale of nations just to function
If we remove PoW to reduce cost and stop wasting energy, it just makes it another centralized system. PoS or FPoS is centralization in the hands of a few whale coin holders.
Many other VC backed blockchains like Solana are not even decentralized. And to talk about enterprise blockchain like Corda or Hyperleger, I don't know if it's even correct to call them blockchain.
Furthermore your analysis of PoS makes no sense as well. I guess you have a lot of BTC?
As it stands, the only blockchains that are relevant are just colossal energy sinks, and it's devastating.

Eh... You're the one defending a system that doesn't give a shit about the ecosystem. You know, the real actual ecosystem, the one POW[1] blockchain so immensely contributes to destroying. It's almost as if you guys are all pretending it doesn’t exist.
