Fanboi discussions and reactions are the norm in the Python community. But this what you get when maybe more than half of your community is made of non-devs, who never touched any other language and never will.
Ignoring the snark and elitism in this comment, it’s unclear to me to why even “actual developers” must touch other languages, if python satisfies their needs.
Programming is a tool, with the goal being building things that help the user.
And this is supposed to be bad because?
They had a problem, used a language to solve it, they've solved it, end of story.
If they're satisfied with their solution, and it works for their purpose (and for their companies/organizations purposes), who is to day it's not OK?
Perhaps they are professionals doing a job, not dilettante nerds trying different languages and idioms for fun...
