True but this isn't specific to the tech bubble. It's a feature of capitalism. Competition forces firms to adopt shorter term horizons. If a firm has significant profit to make by focusing on the short term and it does not, its competitor would. If the profit possoble within this period is significant, having the competitor collect it runs the risk of the current firm failing, or the competitor accumulating enough for hostile takeover, among other failures. That would stop the current firm onwer from collecting profits in the future. Even if focusing on the long term is more profitable over time, firms may not survive in a competitive environment to realize long term profits. These are some of the fundamental processes that drive firms into short term horizons. With liquid asset markets there are even more immediate processes driving firms into short term planning.

Add to that planning based mainly on prices, which don't capture a ton of reality and you get situations like a water hungry datacenter in the desert, cause the price of water does not capture its long term availability for example.

All of this has happened in the past, even a century ago. It's happened and keeps happening in other industries too. For example the fossil fuel industry.

They're locusts. They don't think about anything past the next fiscal quarter.

Because closed loops are more expensive in the short term, making it a non-starter

Closed loop watercooling is really just air cooling with extra steps. The water is heated by the devices and cooled by a large radiator with fans. Or it's cooled with a chiller which in turn is cooled by a radiator with fans.

Replacing the water is the most effective (yet wasteful) way to remove the heat.

I remember there was talks about a floating data center in the ocean.

seawater would probably corrode whatever storage system they have in there overtime, all that biological material, chemicals and gunk.

It's not like they're dunking the electronics in the water. They just need to filter it enough it doesn't clog up the system and run it in a closed loop.

If I can have a closed loop with a reservoir for my home PC, motherfucking Amazon can build a water storage tank for their cooling.

Its an amazon data center in Gilroy, been in the works for a long time but they recently put up the development signs so I think now that they ran the new water lines a like a year ago they are ready to break ground

I'm more worried about humans draining our aquifers that took thousands, even millions, of years to fill. That water is no more replaceable than oil.
