This line of reasoning works adequately when looking at a single program, but when you look at a larger group of programs, performance still matters. The more performant each individual program, the more programs can be run simultaneously. This helps everywhere: mobile (better battery life, smarter apps), desktop (more apps open without swapping), server (more compute in the same footprint), and embedded (smarter devices, less power, cheaper hardware).
