I don't have any specialized knowledge of the physics but I saw an article suggesting the real reason for the push to build them in space is to hedge against political pushback preventing construction on Earth.
I can't find the original article but here is one about datacenter pushback:

But even if political pushback on Earth is the real reason, it still seems datacenters in space are extremely technically challenging/impossible to build.
I don't get why we aren't building mixed use buildings, maybe the first floor can be retail and restaurants, the next two floors can be data centers, and then above that apartments.
Where I live, Norway, we've seen that:
1) The data centers don't generate the numbers of jobs they promise. Sure, during building phase, they do generate a lot of business, but during operations and maintenance phase, not so much. Typically these companies will promise hundreds of long-term jobs, while in reality that number is only a fraction.
2) They are extremely power hungry, to the point where households can expect to see their utility bill go up a non-trivial amount. That's for a single data center. In the colder climate areas where data centers are being promoted, power infrastructure might not be able to handle the centers (something seen in northern Norway, for example) at a larger scale, due to decades of stagnation.
3) The environmental effects have come more under scrutiny. And, unfortunately for the companies owning data centers, pretty much all cold-climate western countries have stringent environmental laws.
