You obviously didn’t watch the video, he literally does the heat transfer math using radiation only, it works just fine.
Instead of just stating “it won’t work” why don’t you actually do the calculation yourself and show why it won’t work?
Yes they have an incentive to put things in space, but it actually is a decent idea if they can execute on it the same way they did with Starlink. There’s huge demand for compute, many data center projects on earth are being scuttled because of NIMBYs and lack of power, there are no NIMBYs in space and a sun synchronous orbit means you can power them without batteries.
