I’ll swing for the fences and argue that no, even with better computers, Communism isn’t going to work. Nor some gauzy vision of post-capitalism that looks like Communism, but with YouTube videos.
In retrospect, Communism seems wildly stupid, or at least, incredibly naive. Did the people who dreamed up this system not understand the enormous incentive problems they were creating? As Ayn Rand dramatized the problem in “Atlas Shrugged”: “It’s miseries, not work, that had become the coin of the realm — so it turned into a contest among six thousand panhandlers, each claiming that his need was worse than his brother’s. How else could it be done?” The incentives of “from each according to his ability, to each according to his need” drive toward falling production, which means there won’t be enough to cover the needs.
Or as a former colleague who fled Communist Poland once told me, “They pretended to pay us, and we pretended to work.” There is a reason that basically all the Communist and Socialist regimes ended in some degree of authoritarianism.
