> I mean look at the first plane, then first air-jets: it’s understandable to assume we would travel the galaxy in something like 2050.

To someone who did not understand what flight is, perhaps. For anyone who understood the laws of physics, no. A similar thing can be said of Moore's Law. The main difference is we likely exceeded the rational expectations derived from Moore's Law (though that was based more on computer performance, rather than the actual expression of Moore's Law in terms of transistor count) while the more rational expectations of flight (routine supersonic, perhaps even suborbital) are still flights of fancy. But that is more a product of cost than technical ability. Simply put, we figured out how to make semiconductors extraordinarily inexpensive. Flight is still expensive.
