Are you sure it's the number of computer-related searches decreasing and not the ratio of computer-related searches to all searches ? That would explain a lot.

Are you sure it's the number of computer-related searches decreasing and not the ratio of computer-related searches to all searches ? That would explain a lot. Computers are increasingly used by people who don't care or even like technology. It even affects my favorite field - computer games. Games for techies were games for problem solvers, geeks, fantasy/SF lovers. Games for mainstream people are quite often mindless fun, sports, or sims. I have noticed this trend years ago, when I tried to compare the popularity of Linux versus other operating systems.
