I think this is sort of a 80/20 situation, where the last 20% of the project is taking 80% of the time to complete -- the project here being the "migration" from the physical to the digital world. That's why change is not so palpable. This project is a great one nonetheless: we're redefining how humans relate to each other, how we handle and share knowledge, how we collaborate. I think these changes affect society in a more profound way than some great new device or technology.
