It's literally a deflection mechanism to the fact they want to build data centers all over the land by proposing a fantastical better way that simply won't work.
That has been covered to death since months, there is no good solution to cooling without an atmosphere. But even going into the technical details is a waste of time, think about how complicated maintaining such a system in space would be compared to having it on earth, the whole idea is a complete grift from beginning to end. There is literally no benefit to do it in space other than as a marketing tool.
Nobody who suggests the idea has ever presented a model that is even remotely close to reality
What a surprise that something this implausible could come from the same guy who proposed trains that run in vacuum tubes.
I can't believe the people who actually listen to this guy can tie their own shoelaces. And somehow he became the richest person on earth. Humans are irredeemable.
