It’s hard to learn the ins and outs of dozens of programming languages. One doesn’t usually just use one or two PL over their entire career. I have worked professionally with at least PHP, Java, Python, JS, Go, and Ruby. That without taking into account the respective libraries and frameworks (and without taking into account as well the myriad of other components like dbs, web servers, caches, etc.) It sounds like an excuse, I know. The true is I just don’t have that much time.
