The best thing about using watercourses as your heat source for heat-pumps - the water flow naturally takes away your "colder" output and brings you more "warmer".
Ground source heat pumps are limited because the ground they have chilled stays stubbornly in the same place, so the only way you can extract more heat from it is to make it even colder, which gets less efficient. Watercourses don;t have that problem.
The opposite effect is also why thermal stations (including but not only nuclear) are usually on the coast or near large rivers: you can dump a lot of water heat into water and have it carried away.
Not always good for the local ecosystem without mitigation, but at least one Japanese reactor allowed local colonisation by tropical fish and local legend said the same about Sizewell.
Sizewell C claims to plan recover waste heat and use it for carbon capture somehow, about which all I can say is a big old hmmmmm.

Not quite the same thing, but there is a tropical greenhouse in the south of France that used to be heated by cooling water from a nearby uranium enrichment facility: https://fr.wikipedia.org/wiki/La_ferme_aux_crocodiles (unfortunately not available in English).
It is, since the obvious alternative to taking the heat from water would be taking the heat from the air or from the ground.
The air is colder in winter than the water, and the ground only provides a limited amount of heat before you can't extract any more. So water beats both.
Even if all that were true, where is the path to profitability for OpenAI, and all the rest? If they can't pivot to making a profit, then they are going to pop, and their investors will lose all their money. That's the AI bubble... investors losing all their money.
The technology will remain, of course, just like we still have railways, and houses.
That is a valid and interesting discussion point. I do concede that OpenAI will probably not survive in the long term. Google and Microsoft on the other hand have dozens of independent verticals and revenue sources. Google can afford to be a loss leader with Gemini AI, and when every competitor goes out of business, they will jack up prices and enshittify a tool everyone depends on. Like what happened with YouTube once Google Video, DailyMotion, Vimeo, and the other sites essentially stopped being relevant.
But, and this is key, AI is not going away for as long as the potential to replace human labour remains there.
I've found usually to poor effect. Both Rust and Haskell did away with .mli files and ended up worse for it. Haskell simplified the boundary between modules and offloaded the abstractions it was used for into its more robust type system, but it ended up lobotomizing the modularity paradigm that ML did so well.
Rust did the exact opposite and spread the interface language across keywords in source files, making it simultaneously more complicated and ultimately less powerful since it ends up lacking a cognate to higher order modules. Now the interfaces are machine generated, but the modularity paradigm ends up lobotomized all the same, and my code is littered with pub impls (pimples, as I like to call it) as though it's Java or C# or some other ugly mudball.
For Haskell, the type system at least copes for the bad module system outside of compile times. For Rust, it's hard for me to say anything positive about its approach to interfaces and modules. I'd rather just have .mlis instead of either.
I don't understand that hate against header files. It is just a separate file with the interface. Of course you also need to change it, when you change the API, which you might find annoying, but maybe you should use that to consider that you are just changing an API?
