I wonder what the economics of water cooling really is.

Is it because chips are getting more expensive, so it is more economical to run them faster by liquid cooling them?

Or is it data center footprint is more expensive, so denser liquid cooling makes more sense?

Or is it that wiring distances (1ft = 1nanosecond) make dense computing faster and more efficient?

It's more of a testament to inefficiency, with rising TDP year after year as losses get larger with smaller nm processes. It's so atrocious, even in the consumer sector Nvidia can't even design a connector that doesn't melt during normal usage because their power draw has become beyond absurd.

People don't really complain about crappy shovels during a gold rush though unfortunately, they're just happy they got one before they ran out. They have no incentive to innovate in efficiency while the performance line keeps going up.
