Haha, you've described today, only those big app-platforms run on the web. I'd prefer them to be native apps. That would be more CPU efficient and devices in turn would be cheaper and effectively more powerful. Can you comfortably run a few of these at the same time on a 10 year old netbook? Not currently.

I'm in favor of retiring the web. Not that it will happen any time soon. How many reasons do we need? Private information leakage alone should not be tolerated. Accessibility? Attack surface? Resource efficiency?

Obviously I'm missing the point, because none of this explains why internet is what it is. I sure wish it were simpler.
