> he tried to use Mathematica to share one of his studies in a way that anyone could explore every detail of his data and methods. It didn’t work. He says that Mathematica’s owner, Wolfram Research, made it too difficult to share his work in a way that didn’t require other people to use the proprietary software, too

Sometimes I wonder where Mathematica would be if it were open sourced lets say in 2010. It had such a head start over Python.

Interestingly, Mathematica interop with Python is basically non-existent today, even worse than it was in the past. Short term moat building destroying long term viability.
