With how shit youtube is I am not sure you made a great case for python mate.
I'm not good with names about logical fallacies but that sure is one. You asked for "actual projects" and YouTube is one of the biggest and most popular platforms out there. That you personally dislike it is irrelevant.
ETL tools can execute python as part of a multi step process and then yeah they use python in their data pipeline, but the ETL tool that orchestrates it is which is the actual value add software is not written in Python it's written in Java
So what's your point, that interpreted languages don't count because they're interpreted? Why stop there? It's the actual C compiler that was used to compile the JRE that brings the value here, so your ETL tool doesn't count.
You're either a troll or a joke.
