I understand Mr. Wolfram's decision to be a billionaire with a small army of brilliant persons at his beck and call. I also understand his desire to keep complete control of what he's built. All that being said, I sincerely hope he makes provisions to make his work Free at some point after his death. Because, if he doesn't, lacking his admittedly ingenius leadership, it will be lost to obscurity at best. That would be a shame for humanity.
