I’m sorry to say that I was shocked by this article. I have no objection to Wolfram remaining closed source - if they prefer that model and want to make money from it then it’s up to them. However, that they feel that they have to justify this by implying that their approach is clearly superior to open source in innovation, long term commitment and user experience I’m afraid leaves me with a rather negative impression (to put it mildly!). A lot of open source is flawed but some disproves these assertions comprehensively. If they really wanted to ‘unify all of computation into a single coherent language’, which sounds like a mammoth task, they would surely welcome quality contributions - beyond just picking up and using other open source projects - from whoever feels able to make them rather than a small group of individuals working in private.
