Is It Really Impossible To Cool A Datacenter In Space?

Yeah, cooling being radiation-limited, and also heating from the Sun, Earth, and elsewhere.

At the end, he acknowledges we haven't even talked about the power supply in space.
 
Definitely worth looking into. Even better would be to optimize the software and require less hardware. Throwing big iron at a problem has always been a knee jerk reaction.

Way back when I saw dueling keynotes Bill Gates and Andy Grove at a consumer electronics conference in Las Vegas. Maybe the precursor to CES. Bill Gates said hardware would always be the compute limitation. Andy Grove said software will be the limitation. Both were right of course.
 
Regarding the power issue of AI, this is what is happening the coming 5 years, off grid if you can.

Very nice overview article in NYT of all that is happening now with the new AI data centres being constructed all over the US.
Has a great image of the new INTEL construction site in OHIO and all the datacentres around it that are being developed.

Why Tech Giants Are Ditching the Power Grid​

Seeking power for data centers, Meta and other companies plan to use equipment that is expensive and polluting.

Industry analysts and executives also question whether power plants built alongside data centers will remain competitive if it becomes easier to connect to the grid.

Siemens Energy makes some of the equipment that the New Albany power plants plan to use. But even that company’s chief executive, Christian Bruch, is skeptical about using smaller machines as permanent power sources.

“These will not be long-term installations,” Mr. Bruch said in a recent interview, discussing the broader trend. “Is it good in terms of efficiency? And is that a smart power supply solution? Absolutely not.”
