>I'm never sure why projects try to claim themselves as a free alternative to Mathematica. In this case it's an open-source project reimplementing Mathematica (though technically only the Wolfram language). >For hobbyists, Mathematica is free on a Raspberry Pi, Also Wolfram Engine (which due to previous technicality is closer to Mathics) is free anywhere. >And secondly, is Mathematica really that expensive if you use it in your job/industry? The point isn't the price but but that an important software used in academic research is closed source. Those that value open science want to have a way to reproduce results using free tools.
