HCI guy here, who gave a fair share of demos at conferences etc. to illustrate new concepts. Those demos are usually held together with duct tape, and would require TREMENDOUS work to turn into production ready apps. Additionally, HCI researchers (group in which I'll include Bret Victor, even though he doesn't publish at the main conferences etc., sadly) are more interested in creating those examples to illustrate their research, but not in building commercial stuff (which is a very different type of work). I actually was at Victor's talk "Stop Drawing Dead Fish", and at the end an audience member asked if he could release it. He said that if he released it, no one would get any use out of it, because it was really built only with that talk in mind. (which, of course, is not surprising– that's the nature of his work) > ' He would not get rich, but I guess he does not need to earn money anymore.' You're greatly overestimating things here, my friend :)
