The sheer size of and resource consumption to build and operate them.

Most people can't really understand the numbers in question due to their size. It's like that picture of 1 million dollars in $100's stacked up on a pallet, then 1 billion and 1 trillion. But instead of worthless paper, it is consuming huge swaths of the limited fresh water on the planet, creating the largest natural gas power plants in the world, consuming huge swaths of the fundamental foundry and fab processes that our entire technological society relies upon ...

And the "literally solving unsolved math problems"... Who cares, how will knowing the answer to that math problem solve our global climate disaster from taking out modern human technologies civilization? It's not!

100% of the water that is 'used up' in a datacenter, or even in electrical generation, is evaporated into the atmosphere. The same one where the rain comes from. Everywhere East of the Rockies, they don't even have droughts, so that seems like a lot of area where we can use a lot of water with basically no impact because it's all just coming back into the water cycle directly as opposed to ending up in a water treatment plant and flowing into the sea.

We'll be able to increase chip capacity eventually, and we're also still doing pretty well at clean energy conversion. Eventually we'll get there.

I'm much less pessimistic about this.

It’s clear you don’t know what you’re talking about. Data centers don’t use water.

Beef consumption dwarfs data centers in terms of environmental damage for no good reason and does much worse things to water, but nobody cares cuz beef is a status symbol for people. AI is easy to hate and requires no sacrifice. But giving up red meat is kind of tough so nobody does it.
