The computer was a great invention. The Internet also is a big enabler. But the latest computers and phones are hardly innovative: Compared to what you got 5 years ago, they might be smaller and have better power efficiency. But on the grand scale, how does that matter?
If you see the latest Macbooks being introduced, you probably want to get one. It's very shiny and the Retina screen will allow you to experience computing in a great way. People try to become happy by spending money for experiences. Tourism, iPhones, hipster coffee shops. They don't do it because it's the universal recipe for happiness and living your life, but because it's what capitalist societies expect you to do. Most "innovation" and "disruption" only leads to zero-sum money shifts inside this system. If you think that a retina screen is innovative, i think you need to get some perspective.
The same goes for cars. The Germans (where I come from) think that they're innovative because we have a few luxury car makers here. Cars in general are great, they provide mobility and that's useful. But how are the new cars better than what was available 30 years ago? They're not even more fuel efficient.
Bill Gates seems to have got it when he stopped working full-time at Microsoft. All over the world people are using their software, but if we were using OS/2 and Lotus instead of Windows and Office nothing would change. It went very well for him and his company, but nothing they ever did was as important for humankind as what Bill Gates is doing now: giving life to millions by completely eliminating malaria and polio from the planet and supporting AIDS and TB research with huge sums.
