Either they are stupid or lying. Both doesn't make them look good.
Also omitting costs like:
- RND. You are unlikely to use off the shelve parts for cooling (radiators?), communications, fire safety, thrusters, you are basically building a satellite for a thing nobody has done before
- maintenance mechanisms. You can't just send a guy to replace the radiation hardened SSD and if you do, congrats you have to build a space station. You could just let it die, but then the math will math different in comparison to a terrestrial data center
- operational costs of satellite control personal and ground stations. Crunching AI in space is nice, but last time I checked the state of AI it needed tons of training data. Have fun paying for that connection into a orbit that has 24/7 solar, as earth is spinning below. Radio stations across the globe.
And these are just unmentioned costs a non-space self-thought tech person came up with in 5 minutes. Don't invest into people this incompetent or malicicious.
