It is not a good idea listening to experts tell you what can't be done. Science and technology progresses one funeral at at time. Einstein's ideas were crazy for classical scientists and Heisenberg's for Einstein.

The most important thing is making space access ten to one hundred times cheaper with reusable rockets. Then a lot of the problems in the article will not be problems at all.

E.g ISS was designed and created when access to space was extremely expensive. Solar technology and batteries was extremely bad but also super expensive.

You can not use convention but radiation works incredibly well and you can also use the thermal technology of mobile devices.

The most important thing being cheap is that access to the Space become possible for way more people with creativity. Not just a few people with academic titles but people with practical engineering and scientific mastery (that certainly run circles around them on real projects).

There are so many opportunities to use creativity in space, with possibilities that do not exist on earth. For example you can spin or rotate things super fast and so you could have convention inside the machines that rotate.

What are the fundamental advantages of space-based data centers over terrestrial ones? Certainly not cooling or radiation shielding. Those are almost free on Earth. A Zero-G environment could have some benefits regarding the total size of the construction, but of course being in Earth orbit means Zero-G but does not mean no gravity. Anything in LEO will require constant station-keeping maneuvers, and the more massive the data centers, the more fuel required. Power generation could theoretically be better, but even if you had a 100% efficient PV solar shield, you still need to radiate away the same amount of energy at a rate at least equal to that to maintain thermal equilibrium.

You could say this is all just a question of materials science, and maybe it is, but it’s not anything that makes any sense at all today, nor is it something I think anyone should expect to be up and running in the next century.
