What Hacker News says
2 sourcesI do computer mathematics. I’m the author of a computational group theory package [2], and my day job is in quantum mechanics and quantum computation, but in that I’m building packages in a software engineering capacity. The algebra gets pretty gnarly. Check out a recent paper, which includes both a math [0] and SW [1] component. Perhaps because of this I’m unusually representative of the intersection between math and software.
I hope folks aren’t finding my comments hostile. I have used the Mathematica product before in their GUI and at the command line, and some of my colleagues use it for various calculation tasks. I’ve opted to stick to open source alternatives like Sage, wxMaxima, GAP, and Axiom/Fricas.
The engine doesn’t give you a license to Mathematica, so I don’t presume the target audience is the collection of folks who want to

do differential equations with plots. The article emphasizes lots of software things (languages, integrations, etc.), so actually I do believe they’re targeting software engineers.
You should note that I have not criticized their features, but rather restrictions on the use of the product in the first place . Maybe that would be interesting to read, but instead I have commented on the leading question in Wolfram’s article. I have not and will not download their Wolfram engine in its current state though for the reasons I’ve outlined. Do recall that using it means I’m bound to a legal contract, and that’s not one I’m willing to engage with.
