The PoS switch by Ethereum has promised for years, and it always get delayed. Pretty much as long as there is money to suck up from someone & greed exists, there will never be a switch.
Meanwhile, while crypto-bros tout all of the perceived benefits they receive from crypto, crypto-bros never acknowledge the past & current waste of energy that crypto consumes, both from an environmental and economic standpoint. They usually point to switch to PoS as how the excessive waste of energy will change, and that has been repeated for many years as already noted above. The tech in crypto isn't something better; what it does now through blockchain has been done far more efficiently by databases. I like the concept of blockchain, but its use by cryptomining is just a wasteful application.
Now, I also know with crypto-bros, it pretty much is useless trying to get them to see the larger picture. They already "know" the big picture. So no need to convince me - it's all good, bro!
