"We know how to vent heat" and "we know how to vent enough heat that this becomes economical" are two different things. Can we deploy computers in space? Absolutely. Can we deploy a shitload of computers in space that are running extremely compute intensive tasks on a continuous basis?
That's the point I'm making.
> Can we deploy a shitload of computers
That's the "is it economical?" question, and to spoil the answer, "with the way launch prices have been dropping in last few years, yes".
(Also the larger question of "relative to datacenters on the ground" is answered by "yes, if you want clean power for it" - turns out moving compute up is more economical than beaming power from space, and costs down here are becoming dominated by land price anyway.)

"Extremely compute intensive tasks" is just elaborate and overspecific way of saying "requires N KW of power".
There is nothing magical about compute here, power is power - it doesn't matter whether you spend it on ML, or collecting photons and radioing them back to Earth, or broadcasting a high-precision clock. You need some N KW to run = you need to collect that much, and you need to reject that much of it as heat[0].
