We're going through an inversion of scale in computing which is making parallelism and concurrency much more important. Single computers are no longer fast enough to handle the amounts of data we want to process. Even within one computer the relative speeds of processors, memory, storage, and network have diverged so much that they often spend more time waiting for data than doing things with it. The processor (and by extension, any program we write) is no longer a Wizard of Oz kind of character, sole arbiter of truth, at the center of everything.
