The only issue with central planning is making people behave according to its rules - it's a problem of motivation. The calculation side itself is evidently better under central planning. Free market is an optimization algorithm and many other exist. It's extremely unlikely simulating prices is the most effective way to allocate, but even if it is, it can be done more efficiently by simulating the process without real world waste.

Everything is slowly centralizing already - some markets remain to provide motivation, but the trend is in the central planning direction.

Given better technology, free markets will definitely die. It could be solved as directly as by overwriting the internal motivation through some brain implant, making people happy to work for the good of the system.
