But snark aside.
Hopefully in the long term PoW will eventually be abandoned altogether... aside from BTC and maybe some inconsequential stragglers. But this is a very big nuance that people refuse to address. All blockchains are evil, period. I've seen people outright dismiss the fact that eco-friendly blockchains exist, even when linked to Tezos' wiki's energy consumption explanation. [1] Their opinion is that no matter what, blockchains are a bloated solution because it's an append only database replicated across the globe. But what they fail to understand is just how much redundancy is hidden from the user in the traditional web. Just think that every website has a database, likely replicated and with multiple backups, with all the infrastructure to keep it up and serve its data, all of which is likely not optimized at all because hey, as long as it works. For each and every website!
On the other hand, blockchains are likely highly optimized for their use case (well, aside from Ethereum), with no need for backups, replicas and all that jazz as it's already built in the protocol. Consider also that traditional websites' servers have to run 24/7, even with no visitors.
Sadly, NFTs completely shut down any possibility of rational discussion, but in my opinion blockchains are breaking ground for new ways to develop websites by using decentralized, highly optimized, shared infrastructure. (Example: The Graph[2])
We'll see.
