Programmability only matters to users who can program - which is a tiny minority. There is no sense in which HN or a PhD-packed centre like PARC represents the interests of typical users, who are perfectly happy to use relatively dumb information appliances that can only be customised with ready made applications controlled through some vaguely graphical UI/OS. PARC's real legacy was the creation of a workable model for non-expert UIs. The Smalltalk/LISP angle was never going to be more than incidental. I'm personally a huge fan of it. But it's completely opaque to a typical user and always will be. AI promises to be at least as transformative because it won't be long - more than five, less than ten years - before it allows complex customised context-aware task-oriented voice commands that aren't mired in the thousands of random switches, file location inconsistencies, and other dinosaur bullshit of the UNIX command line.
