Anecdotally, I've used Mathematica a bit for prototyping ideas over the years for various computational model prototyping purposes. I rarely see anyone else using Mathematica though, I often too wonder who their typical customer is (outside of educational institutions which its a good fit for). I find it's great for prototyping certain types of ideas (more abstract/mathematical in nature) because there's a wide range of useful and complex functions that allow you to piece together ideas quickly, iterate/change, and test them. It's quite powerful in that respect. Sometimes I have an idea and don't want to dig around dozens of libraries, dependency chains, etc. to piece some proof-of-concept test together, nor do I want to attempt to implement everything needed from scratch because that could require a large time investment (and fail conceptually). Some similar efficient prototyping workflows can now be accomplished in Python using Jupyter/JupyterHUB, at least for me. Any of my successful prototyped ideas immediately left the Mathematica ecosystem to be implemented using other technology stacks.
