I knew Wolfram was a massive asshole, but I didn’t know or forgot that Mathematica was based on appropriated publicly-owned work:
In the mid-1980s, Wolfram had a position at the University of Illinois-Urbana's Beckman Institute for complex systems. While there, he and collaborators developed the program Mathematica, a system for doing mathematics, particularly algebraic transformations and finding exact-form solutions, similar to a number of other products (Maple, Matlab, Macsyma, etc.), which began to appear around the same time. Mathematica was good at finding exact solutions, and also pretty good at graphics. Wolfram quit Illinois, took the program private, and entered into complicated lawsuits with both his former employee and his co-authors (all since settled).
and on that note, Symbolics did effectively the same thing with Macsyma (and a ton of other public software on top of that, all to drive sales of their proprietary Lisp machines), but a modernized direct descendent of the last publicly-owned version of Macsyma named Maxima is available and should run wherever Common Lisp does. it’s a pretty good replacement for a lot of what Mathematica does, and the underlying language is a lot less batshit too
the thrill of UB: you try to dereference a C reactionary but get a lambda calculus neoreactionary instead
