People say sometimes, ‘You work in the fastest-moving industry in the world.’ I don’t feel that way. I think I work in one of the slowest. It seems to take forever to get anything done. All of the graphical-user interface stuff that we did with the Macintosh was pioneered at Xerox PARC and with Doug Engelbart at SRI in the mid-’70s. And here we are, just about the mid-’90s, and it’s kind of commonplace now. But it’s about a 10-to-20-year lag. That’s a long time.
