I think you may be placing too much value on the output of these machines which use tons of energy, generate pollution (both noise and chemical), and generate output that's worse then what a human can do. We would be better off if these LLMs didn't exist.

Average person in US reducing his/her meat intake by 1/4 would do much, much more for environment compared with completely scrapping entire AI infrastructure worldwide. For some reason people concerned with environmental impact of AI get really angry whenever I point this out.

The average person here would do more still by just taking one less flight. It's air travel that really blows individual emissions out of the water.

I think it would obviously better for society.
