In my observation, this demographic is most densely concentrated in the JavaScript community. Not sure what that says about the language itself, but there’s definitely a glut of unprofessional JS devs out there.
Ooh back in my coding days it was PHP. And before that in my undergrad years was Vb6 ... which provided me and several other programmers with lots of frustration and consulting hours to fix the mess the owners' kid made while "programming" their new CRUD system.
There will always be a "cool new" language attracting newcomers and kids.
