Undersea datacenter dulled with nitrogen has failure rate 1/8th of land-based systems. Good reminder oxygen is a a ridiculously dangerous nightmare chemical killing everything we build that humans breathe for fun. https://www.bbc.com/news/technology-54146718

If you take a civilization that did not evolve in an oxygen atmosphere they would treat Earth the way we treat the surface of Venus

You, human, are not the future victim of an outsider existing beyond cultured existence and reason. You are not the imposed-upon subject of fate as your stories cast.

You are the nightmare creature living in acid that disintegrates everything it touches.

You are the alien.

Something @krenaud mentioned is cosmic rays. Water is way more dense than air. Not saying this is any explanation but it may be a fringe benefit of ocean datacenters.

I’ve seen it said that swimming in a nuclear waste pool is less radiation than standing on the surface of Earth.

Yes, domestic nuclear radiation and cosmic rays are often different classes of emission, but dense materials have an effect on both.
