This is FUD and rarely happens in the real world. (It happens with about the same frequency people abuse language features in other languages, like monkeypatching Python classes in an uncontrolled way, which is just as bad.) Not once in my career have I heard someone either inspect or begin to learn Lisp and said “ya know what, all these new languages, not for me.” People usually don’t learn (Common) Lisp because it’s an old language, people don’t recognize benefits it has vis a vis other langs like Python/Go/Rust, it doesn’t look like anything they learned before, it more-or-less bolts you down to Emacs, it has no major corporate backer promoting the language, etc.
