That is like trying to model the exponential growth of laternfish[1] by emulating the behavior of each individual fish and then claiming it impossible to compute on consumer hardware. (The reference might sound like "word salad" if you have not participated in the last advent of code, it was just the first example that came to my mind. The point is, just because some naive approach at computing something is not realistic, does not prove the problem to be impossible to solve.)
For example here is a modern piece of software that can create a five years plan in reasonable time:

But anyway, you missed the point of my "word salad". People have to obviously plan in a free market. I will not be successful if I just produce things blindly, or at least it will be pure luck. Would you say that success in the free market is purely based on luck? Maybe part of it, for sure, but obviously it is possible to plan ahead, to determine and model demand and so on. While overproduction is impossible to avoid in a free market economy, most companies at least hilt the general ballpark, they will produce a bit too much but not hundreds times too much or they wont stay in business. So obviously planning does happen by the individual actors, they do calculation. They do the work that individual miners in a bitcoin network do, hence the metaphor. The free market itself is a giant computation engine, that solves the problem of economic planning through the interactions of the individual actors of the economy. A very crude machine but it solves it. From this it follows that economic planning is obviously possible and can be solved.
> This claim is complete insanity. At no point in history the USSR has performed better than the first world in any sector, with the exception of a few propaganda stunts (like the space race) that came at costs so enormous that could only be borne by a brutal dictatorship, and that were promptly and easily matched and surpassed by the US.
The comparison is meaningless, as the Soviet Union and the US had vastly different starting conditions. If one country is economically stronger than another, it does not follow that the economic system is better or worse as many factors influence performance. If we run a 10k race against each other and you start from the beginning while I have a 5k lead before the run starts, it does not follow that I am the better runner.
The Soviet Union started as one of the least developed areas of this planet, literally still using the wooden plow and was devastated by two world wars and one civil war in a short period of time. It even being considered a competitor to the US is more that a miracle.
Could it be that your views on the efficiency of central planing are more based on prejudices that looking at actual empirical data? And again, we are looking at the most naive implementation of central planning. This is like judging the speed of garbage collected languages on some weekend project.
