Also, there is a bit of a difference between a high school student, a college freshman or sophomore (<21) and someone graduating college (22,23). Small numbers, but there are different degrees of experience, maturity, and being just a little more past the "exploratory" phase.

This would make successful founders tend to be older than unsuccessful founders, but it's like always finding something in the last place that you look, or (happened to me) you're most likely to get injured on the last ski run of the day.
Let me FTFY: once you start a successful business, it's unlikely that another you start will be nearly equally successful.
Most entrepreneurs are serial ones, and successful ones -- particularly those who leave their business behind (e.g. by acquisition) tend to try again. But contrary to popular belief, having a successful business in your past doesn't make it easier to make your new ventures successful -- it just makes it easier to start one.
EDIT: this was a \s piece but obviously it went over some peoples heads lol
Propagating nonsense about needing to have deep understanding in widely different fields (ML! DevOps! Frontend!) is not only patently wrong, it is needlessly discouraging.
By which time the web crowd will have moved on to something else.
