Even with well distributed knowledge, you'll still likely end up with 1% of the population controlling 80% of the resources, which would mean they'd have plenty enough to quell any insurrection from the common people. It doesn't matter if a million people have the skills to cobble together a few war bots each, when a few oligarchs each have a factory and supply chain capable of churning out a million each in the same time-frame.

If it comes to that. I'm still somewhat hopeful that democratic processes and altruistic members of the elite will sort things out in the next century.
