I don't "believe". I'm arithmetically sure that it is going to happen, and it will beat the ground based on pretty much all metrics. Some of my comments with napkin numbers https://news.ycombinator.com/item?id=46882199 https://news.ycombinator.com/item?id=46880680 https://news.ycombinator.com/item?id=46880486
Just a very rough primitive illustration - a land for a house in SV is like a $1M, and putting a 10 ton house into space at $100/kg - $1M. Existence of supposedly cheap land somewhere (with not much infrastructure usually) doesn't help as you put your computer nodes into a datacenter building with all the required infrastructure which cost more than the SV land on a sq foot basis.
And that is without consideration of how powerful a weapon is the energy generated by a humongous field of solar panels in space. Remember Reagan's Star Wars? Nuclear explosions as a source of power for the direct energy weapons like lasers, etc. Well, you wouldn't need the nukes anymore. Just redirect a bit of power from your compute nodes. And as i already wrote, the large transnational companies will have to take care about their own defense themselves https://news.ycombinator.com/item?id=47981423 - one more "feudal" aspect of the coming techno-feudalism.
Defense is one of the most important sovereign aspects, and upon acquiring it the transnationals will be able to acquire pretty fast the other sovereign aspects. Like enforcement of the Criminal Code of the Mars Colony - again pretty rough primitive illustration of course.
The feudal Europe emerged on the outskirts of the Roman Empire, and in our world the new order will be emerging faster on the outskirts (i.e. where reach and strength of the existing order is weaker), the space being one such "outskirts" dimension and the AI/hypercompute virtual world being the other.
To the commenter below with reddit link : they use human env temp for heat radiation estimate. That lowers the numbers and requires AC equipment. Ie they estimate space station, not datacenter
It's pretty easy to de-orbit satellites or space-based stations. An SM-3 could smoke the ISS pretty easily, and they cost like 10M and we have thousands around the oceans.
But what do you do with all the waste energy? All those MW and GW have to end up somewhere and radiation into a vacuum is the hardest way to dump heat.
Terrible math is terrible.
Better napkin math that is still being unrealistic compared to the true costs of space-based datacenters: https://www.reddit.com/r/theydidthemath/comments/1quvbi4/sel...
Just contemplate what the radiator array and solar array needed a 1GW datacenter and all the cooling equipment and coolant, and imagine the harsh environment in space degrading it constantly.
The only point of the space-based datacenter idea is to pump the Spacex IPO
