The problem is, they need so much more power than a Starlink satellite that they need to be placed in a sun-synchronous orbit. The orbits that Starlink satellites need to use are nothing like the orbits that would have to be used for this rejected attempt at an Ed Wood sci-fi tribute script.
And if you accept that the duty cycle of the AI+Starlink satellites will be less than 50%, it would be much better to build the data centers in random deserts and wastelands on Earth and use the Starlink network to talk to them.
