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.

Interesting point actually. yeah, when spacex was trying to build a reusable rockets, many traditional rocket scientists said that even if you are able to recover stages of the rocket, you still need to refurbish and test a great number of parts, and it just isn’t this panacea for lowering rocket costs (for example, the space shuttle, which was reusable spacecraft, but was super expensive to launch).

When spacex finally got falcon 9 reusability working (and am no expert in this) but from what I read, the pundits were partially right and partially wrong. Yes, refurbishment and testing on the Falcon 9 does cost a lot, but it still brings down the cost significantly (just looked it up, their saying nowadays, the cost savings is something like 70%, which actually is huge). And as importantly, you don’t have to build a new rocket for every launch, and once you get your refurbishment process down like clockwork, you can relaunch them quite often.

So maybe data centers in space won’t be like ones on earth, but they still might be very useful… One idea is that they could become true “space” data centers, that supply powerful computing for satellites near by. This way satellites could get access to much more powerful computing, while still being small themselves (but again, am no expert in this, so maybe this idea also has many holes, for example why not just offload processing to ground based data centers).
