As one who understands spacecraft power budgets, I would ask that you prove your assertion. Spacecraft using solar power have limits and the biggest draw on power is transmission. Small satellites like these will have challenges, but that’s minor compared to the other challenges like radiation hardening would be (cost prohibitive) to be robust to a radiation attack. Mission assurance is a real thing and that costs money.
Small nuclear power generators are the solution for terrestrial AI centers, and in the end, everything in space costs more than on the ground.
But again I ask, what qualifies you to assert my comments are not sensible? You are jumping in and saying I don’t know what I speak of but you haven’t shown yourself to be anything but a basement quarterback.
