There are other factors too, for example I can't imagine that there are many protests in China against building data centers.
I don't see why the same couldn't happen if they let datacentres drive up energy costs or have other widespread impacts.
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
So, plonking data centers into the desert (or on orbit) isn't really a silver bullet, is it?
I don't know if they're actually building AI DCs out there, but it doesn't seem completely unreasonable like you're suggesting.
Of course it doesn't seem completely unreasonable to build out power distribution, cooling, and high-bandwidth network interconnects throughout a region, but once you've done that, you are no longer facing the empty, barren desert scenario.
So if China builds out infrastructure that can be maintained in perpetuity, then more power to them, and the NIMBYs won't have a leg to stand on.
Conversely, in these United States, I've seen literal tons of data centers being plonked into urban centers: literally at intersections where lots of people drive by in daily commutes, there are data centers now where there weren't before, and they are also found on the outskirts of civilization, because they require more security than accessibility. So data center siting can take multiple factors into account here, depending on their purpose.
And can we please stop hammering on the "AI Data Center" meme, because in my experience, a DC is a DC, whether they choose to make it AI or not AI, they're probably all AI from now on, but it just adds fuel to the Luddite fires to say so...
