It's interesting that you mention some of the other emerging careers like "Influencers", because there is a lot more capacity for innovation in these emerging careers. A lot of those industries involve consulting, software, and even hardware products that can give one aspirant an advantage over the competition. If you selectively look at capacity for innovation alongside productivity, YouTube, SEO, and other "new" industries are a much greater boom for the economy than Postmates and Uber. Gig economy apps are not an open platform. Workers are in the thrall to their company of choice, and there is no upward mobility. Even a manicurist may be able to learn new techniques or save money to open their own store, but the app that told a stranger to buy Wimbledon tickets for you doesn't provide a plan for the worker beyond going from gig-to-gig.
