Are you implying air pollution in China is not bad anymore? I wish that was the case because I would visit a lot more but you need to educate yourself a little bit just go look here: https://aqicn.org/map/china/
I'm sure it's better than it was before and it's not India bad but it's almost always considered unhealthy in most parts throughout the whole year
I don't see why the same couldn't happen if they let datacentres drive up energy costs or have other widespread impacts.
