(Before you reply with the usual "Ethereum devs have been promising PoS for years" line, I will tell you this: I pledge to drop all work on Hub20 if Ethereum doesn't complete the transition by the end of the year.)
Not for all blockchains. If that is the point of contention in regards to crypto, then just look at the many other blockchains that do not use PoW.
Have you been living under a rock for the past several decades? Or is this only a thing in EU? Every single fridge or TV sold has an energy class rating. Apple's new processors are all the rage because of their performance per watt. We use 230v (rather than 110v) AC because it's more efficient over medium-distance power lines.

The car uses energy to move mass, it's almost the textbook definition of work in physics. Cryptocurrency is based on proof of waste - you must provide a mathematical proof of pointlessly wasted CPU cycles to conduct transactions.

"All lives matter."
Why not two months from now? That's when they'll be done, right?
If everything goes well and according to plan, yes. But I am not going to make harsh decisions based on best-case scenarios.
