Anyone who thinks we’ll have data centres in space before we have a civilisation changing step up in surface to orbit space drives and materials science is an idiot.
How the hell does anyone think a rocket is ever going to compete with a prime mover towing two trailers, or an ocean going vessel.
We’re not exactly short of land.
And no, space is not cold.
But we have and had ample evidence of flight in nature, we just didn’t understand how it worked. A similar search across the observable universe reveals no sign of FTL behavior.
Sometimes when you understand the science a comparison to some time when people didn’t isn’t as moving or compelling as you seem to imagine.
We will have space datacenters some day. But I'm not holding my breath.
