Well, I think we'll have disagree here : you take on the calculation problem is the opposite of both my theorical framework and practical experience of industry (I work as an Electrical Engineer).

You can try to predict the demand of course, but the prediction is always fairly different from reality. Often, it's workable. Sometimes it's not.

But to be honest, the Economic Calculation Problem is ill-named, because from a Signal Processing persepctive, it's not really a processing power problem. No, the problem is in the Signal-to-noise ratio of the signals used to do these calculation.

Ultimately, if you have a very noisy signal (and economic signals are incredibly noisy), there's really not much you can do with just more processing power. And I have good reason to believe (based on Psycho-social understanding) that the way these signals are transmitted in Centrally Planned system (socialist or not), are particularly noisy themselves. Much more than prices-and-market based systems.

That being said, I don't think we'll see eye to eye here. Thanks for the discussion tho, it is always interesting to hear how other people think.
