This is actually a worry i have about in regards to crypto, the BTC network uses a staggering amount of power.
Ai is next of my power hungry worry list.
Actually, bitcoin uses a ridiculously small amount of power for what it provides. See for example here https://www.lynalden.com/bitcoin-energy/ for an introduction to clear up this misconception.
So far it seems that Bitcoin mainstream use is to create speculative markets. Any other intended objective is a drop in the bucket.
Bitcoin purposefully wastes lots of energy to provide something of extremely dubious value.
Maybe you should stop flying on airplanes for the rest of your life?
Crypto has alternative consensus methods available today and a former PoW blockchain (Ethereum) was able to cut their emissions by 99.9% by moving to a efficient alternative with Proof-of-Stake. For crypto it is possible.
AI (Deep Learning) on the other hand has no efficient alternative methods available for training, fine-tuning and inference and continues to waste tons of water and consume more resources.

It should be the main concern. The top of your list even, hence the aforementioned points today. Deep Learning has no efficient solutions to its energy problem which remains to this day after decades of its existence.
