Hopefully the trend towards decentralized sharing and problem solving will enable everyone to find a niche of 'value' which can be sold/exchanged on the open market. However, given the 'winner-take-all' aspects of the digital age, most people will end up consuming services and product from a handful of best producers. This is great for efficiency, but does raise the problem of keeping everyone else productively engaged. Perhaps reward of non-monetary value (like volunteering with elderly, injured and sick etc.) can be achieved and spread some of the massive productivity gains we will have through automation and the cheap availability of super-star talent through digital scaling. I can't see a system based on charity from the economic winners creating a sense of individual engagement. People need to feel like they earning / creating / contributing something to be healthy over the long term.
