The reason I might find Mathematica interesting is its language, which I found to be on my popularity-brevity Pareto frontier.

So, it can express an average Rosetta Code non-math task in ~180 bytes, compared to Python, ~270, or Java, ~420. I guess this is because of its vast libraries of "batteries included".
Where it all falls apart is sharing. Nobody can run my creation, and even Mathematica Home Cloud is $194/year, which I find pretty steep, being used to free & libre software.
Monetizing is a whole different story, with commercial licenses starting at $1620/yr, which I could only justify if I already had a team wanting to learn the language and a large-ish profitable business service whose source code I wanted to convert to a locked-in solution for some reason.
