I was listening to an interview with Elon Musk tonight, visionary behind Paypal, Tesla Motors and now SpaceX. He was going over his early career. In 1995 Musk approached various venture capitalists on Sand Hill Rd for his latest internet venture and was met with universal skepticism. In Musks words, nobody on Sand Hill had even heard of the internet.
Think about that for a minute. Within 10 years of 1995 the internet would play an integral role in almost every US citizens life (and a good portion of the globe). And the men and women who would be hailed as visionary investors reaping untold fortunes..were completely unaware of it.
While we may not see another revolution like the internet in our lifetimes, you can never discount innovation. There's always the possibility that something is around the corner which would propel the economy forward in ways that we can't even imagine today.
