It is not due to deployment options. People put all sorts of stuff in docker containers every day. It is rather that few people make an effort to learn a lisp, and fewer still who choose to learn Racket. The few universities teaching good computer programming basics using Racket don't really make a dent. You simply don't have coworkers who know this stuff. Are you going to be the one person making a decision at the company, to use something no one but you knows? Not gonna happen. I have not had a single coworker, who has even started to learn these things, even after I have presented a Scheme on a Friday afternoon, and showed off some cool threading/pipeline syntax-rules macro, and showed how this compared to Python, showing how it reduces boilerplate in a way impossible to do in Python. Granted, this is in Germany, where CS education is not really all that great, and most universities teach boring Java or C++ or something. At least we had a RacketCon in Berlin some time ago, and I was fortunate enough to have a prof at university, who at least introduced Dr.Scheme. His motto was: "I am not here to teach you C, Java, or Python. I am here to teach you computer programming." (translated) He went on to introduce languages of various paradigms, from Prolog, to Dr.Scheme (predecessor of Racket), to C, and Python. Thank you Prof. von Löwis.
