Friendly reminder: It's easy to forget there are many more people in the world that write code and are *not developers* than there are professional software developers. Scientists, journalists, lawyers, activists, med. doctors, writers, educators, artists, designers, and many others, can create computer programs!
This paper from 2012 shows an 2005 estimate (for 2012) that there are almost 4x more people programming ("end user programmers") than professional programmers https://dl.acm.org/doi/10.1145/2212776.2212421
