True but on the other hand it is really impressive how Stephen Wolfram managed to build a viable company around scientific software.
Basically he did it by developing the first version of Mathematica when he was a professor at the University of Illinois. They were not pleased (although they've settled since and Wolfram is still headquartered in Champaign-Urbana near the campus)
Impressive indeed, but it makes sense if you call it "Wolfram-Jupyter" and you notice the guy made it 20 years before it was cool.
