They have made 80% of all satellites in space. The other XAI engineers have been involved in making about 10% and soon 30% of all earth based AI data centers.

The space radiator is too small objection usually treats space as a room-temperature heat sink and forgets that rejection scales with T^4 and that the 110 m² panel radiates from both sides.

The knife-edge radiator is between the two solar wings. Mach33 / Vlad Saigau reconstructed the same diagram from first principles and got the same thermal story SpaceX is describing. A ~2.1 ton satellite, ~532 kg in the thermal system (~25% of mass), 110 m² radiator at a proven 2.5–5 kg/m² areal density, and Musk's 1,400 W/m² figure implying chips near 95 °C.
