I like to imagine that at some point we might collectively have a large enough software development population to solve most significant problems comprehensively enough -- and fairly and equitably enough -- for most people that we begin to see developers with increasing amounts of free time. At that point I think we could collectively really begin digging into some of the huge backlog of software bugs and errors that we've built up over time and make everything more reliable, seamless and consistent. It'd be a massive undertaking, especially to solve each issue thoroughly and without causing negative externalities elsewhere. But it'd also be a great puzzle-solving and social challenge, not to mention an educational and useful one.
