But I thoroughly agree that they are the two (one?) biggest revolution in history.
The UI layer is all still prototypes. The economic layer, very early prototypes. The programming languages are prototypes. You can tell because <1% of the population can even use them. Imagine what cars or T.V.’s were like at that penetration. We have barely begun.
I'd argue that nowadays there are more people that use the internet/smartphone devices than there are people that drive cars or watch TVs.
Internet usage has far overtook both cars and television by now. Nobody cares about programming languages or "UI", just like most people that drive cars really don't care about the internals of the engine.
