I don't consider myself leftist (or rightist or any -ist) at all, I try to evaluate all the concepts on their merits. At the time of writing my original comment it seemed to me that computer-based central planning could be a good solution for some problems. Responses here brought up some arguments that made me reconsider the extent to which such central planning could be successfully applied. Maybe inefficiency is a price worth paying for increased resiliency and ability to adapt to environment without explicit specification.

I'm definitely not buying into the principle that everything needs to be distributed, libre and democratic. There are too many obvious failure modes there. Empowering everyone is good, but empowering everyone to the point when a random nutjob can kill millions with a home-made bioweapon doesn't. Nor the coordination prolems like tragedy of commons, oh so present around us everywhere, and one of the primary reasons things are being regulated.
