Orbital datacenters is a hypothetical infinite money glitch that could exist between the times:

- after general solution to extra-terrestrial manufacturing bootstrap problem is found, and, - before the economy patches the exploit that a scalable commodity with near-zero cost and non-zero values can exist.

It'll also destroy commercial launch market, because anything of size you want can be made in space, leaving only tiny settler transports and government sovreign launches to be viable, so not sure why commercial space people find it to be a commercially lucrative thing? The time frame within this IMG can exist can also be zero or negative.

The assumption is also like, they'll find a way to rent out some rocks for cash, so anyone with access to rocks will be doing as it becomes viable, and so, I'm not even sure if "space" part of space datacenters even matter. Earth is kinda space too in this context.
