Thanks for your comment. I wrote a bit about what a Superintelligent AI scenario may look like here. The incentive to accumulate wealth will be up to the individual. If people are given a little bit of a safety net, in terms of money, research shows that people are smart enough to invest it. Investing it by bringing their creative ideas to life with the help of AI, VR, and other emerging applications.
You don't have to be an Elon Musk to bring something of creative, or intellectual value to society. When people spend more time doing the things they cherish, they take more risks and make better decisions about their well-being, it's self preservation. We are born creative, society and the education system drills it out of us.
