Current comp is ultimately because computers and the internet are both the entertainment medium of choice (displacing film, radio, TV, and we know all of those industries and the supporting industries they spawned were huge) and a universal personal and business tool (with an impact as great or greater than the automobile did on both personal and business transportation and, as before, we know how big the auto industry and supporting industries became). Computing and the internet are so fundamental now that I do not expect this wave to stop until every person on the planet, no matter what their local standard of living is, has a personal smartphone within arm's reach 24/7.

We're not guaranteed to have no bumps along the way of course but, over the long term, it's really hard to envision a case where demand for developers, and consequently comp, drops drastically before this global saturation occurs.
