Normal distribution and programming language adoption

One may be still in doubt with the reality and truthness of the theory behind the normal distribution and its bell curve but it explains so many natural, social and economic things like how technology and product are adopted distinguishing early adopters and laggards… it can appear clearly when you do a survey a look at the data you got like this survey done by stack overflow that was not intended to prove this fact but to know developers better but guess what If you look at how and when people are adopting programming language and you don’t see this bell curve you better have to look for lenses or a pair of glasses.

You cannot be seen until you learn how to see.

Here is the bell curve.

Sorry inverted bell curve.

I am an early adopter of programming with Pascal but it doesn’t mean I one of the best programmer far from that but I think I learned how to see.
