Ah, a relief. Not that I doubted that S.W. is a reasonable person but open source vs closed source is such a… “religious” topic. :-) Collaborations in Wolfram

Ah, a relief. Not that I doubted that S.W. is a reasonable person but open source vs closed source is such a… “religious” topic. :-) Collaborations in Wolfram language will be a pretty unique experiment, for they are likely to unite people from very different fields (including, of course, lots of non-programmers). It's going to be great.
