I'd love to learn C++ and jump ship from the Data Science job I work, but I'm not even sure where I would start. Sure there are lots of videos about programming in Modern C++ but the reality is none of the codebases you work on will probably use. And a lot of places just use a subset of C++ or just C with classes, so then how much of C++ do I actually need to know? That coupled with the fact that they are paid less, makes me think I should just learn a python web framework since I already know python, and some Html and CSS and just apply to a python job
