There’s been a lot of technological progress since the Soviet Union’s demise.
There’s probably some point where running a full command economy becomes feasible with modeling, oppressive surveillance and repression, etc. Not sure I’d want to live in it, but “the Soviets failed” is a weak argument.
A command economy gets a lot easier if you can force people to work certain jobs and produce certain things. The Soviets had trouble with this because measurement and enforcement were challenging; they'd have loved Amazon's warehouse worker surveillance systems.
What we have under "capitalism" is essentially the Soviet wet dream: being able to force workers into work, "willingly", and they work so hard they piss into bottles to stay on target.
We've got all the repression right now, just for a slice of the population that everyone considers effectively disposable.
