It's non-trivial to compare cell phones with the combustion engine or flight, but I think we can agree with Kasparov that more inventions of that magnitude are something we should strive for.
Yet engines are actually getting replaced by other alternatives, but those alternatives require different sets of infrastructure which are non-existent (such as for fuel cells or electric cars) Also, there are external forces driving the way to the opposite side of the story (aka keeping combustion engines, for money, of course) Sometimes I just think that the Americans use too much cars (one person driving a car wit…
