There are new blockchains based on technology a million times more efficient than Bitcoin. Ethereum is trying to upgrade. Bitcoin is terrible, but this is fixable by using things other than bitcoin.
That is still a million times less efficient than existing solution and still horrifyingly wasteful. Blockchain principle is that if you have as many people as possible waste an astounding amount of computation and energy, you make over-ruling most of them too wasteful to be possible. You are not solving anything that way, just showing off that you have never heard of Kwakiutl.
There are blockchains now that are designed to be optimal for what they provide.
The bigger issue is that there are applications running on chains that clearly don’t need the features of the chain.
You are advocating for the end of the world as we know it within ten years.
Google might build some of their data centers up in Iceland, but that’s not the full picture.
Then you would not know what you are talking about.

No, they have dozens of data centers, on every continent, and all of them are in areas with cheap, carbon-neutral supply. You think that you are being smart by being dismissive about their effort, and the effort of dozens of companies who host their own infrastructure, but that condescension and lack of expertise is just one more example of why Crypto advocates are so unconvincing.
Unsure about the former point.
More centralization (AFAIR you need 32 ETH to get started, so ~$100000, not to mention possible issues where you loose full 32 ETH) vs a single GPU with only lose is your electricity cost.
