I have a suspicion that most adults (75%+) could pick any skill—excluding sports—and work their way into the top 10% in the world simply by working exclusively on it every day for two years.
But almost nobody displays that degree of focus, so we will never know.
The world is moving toward globalized and hyper-connected financial interests (community and geographically based). Despite that fact, there is no crowdfunding platform built for the kind of deep, impactful collaboration that will happen over the next +10 years.
