I'm an academic, on the humanities/social sciences side of things, and I have the impression that a fair proportion of my colleagues are power users as you define it. They don’t do programming per se, but they customize their software, write macros for their own use, and may occasionally venture into the command line. I fall into that category myself. I don’t know any who are smartphone tap-only users. My colleagues in the sciences are, not surprisingly, even more computer savvy, though I don't know how many do actual programming. Five years ago, there was a literature professor in my department who didn't even use a computer and had to be contacted by telephone, fax, or—gasp—a handwritten note slipped under his office door, but he has since retired.
