Have you seen a little piece of software called Python that basically single-handedly ushered the age of AI? What did Wolfram do except playing toys in his high walled sandbox?
Figuratively half of the comments under this post are "I guess it's cute but I can't see anything in there that I couldn't do with Python".
People pay for so many idiotic and irrelevant things that this is barely an argument in context of any other than hustling. Especially if you consider corporations and institutions to be "people".
For all of Wolfram hubris, Mathematica is just the third kind on the block, after Matlab and Maple. With his ambitions he was obviously aiming for something more culturally relevant.
