The share of young high tech companies seems pretty consistent over the decades, with the exception of dot com, which was no doubt an aberration. Not the norm.

The share of young high tech companies seems pretty consistent over the decades, with the exception of dot com, which was no doubt an aberration. Not the norm. Also, it has ALWAYS been a tremendous risk and challenge starting your own venture. Likely always will be, because there is also tremendous rewards for making it happen. If anything, right now seems like one of the easiest / best times to start a high tech venture in history. Plentiful angel and VC capital. Incredible resources and examples teaching you how to do it (YC, incubators, internet). Flexible tools that can scale up and down depending on company size / need (AWS, open source technologies, facebook / google ads). To put things in context, I just finished Shoe Dog - the story of Phil Knight / Nike - back in the 60's they didn't even have the concept of VC. His biggest challenge was just getting someone to loan him a little cash so he could finance his inventory which was flying off the shelf! The point is that entrepreneurship is destined to be about tackling a very hard problem that nobody else has solved before - in the 60's that was simply getting financing to fund expansion. Today it's something different. In both cases though, it requires being on the edge and pushing the boundary. I would rather be alive today, playing this game. While the gatekeepers are still around, they have much less power than they used to.
