the human race will get the flying car and the fusion when it is ready for it ( technologically these innovations, at the level of successful prototypes have existed for last 50 years). What would we do with such technology if it was in widespread use today? Flying car - sprawl development even further. Fusion - com'n, are we ready for a wide availability of a high flux high energy neutron generating devices? We are still can't control ourselves when it comes to the dynamite and the similar levels of energy, and it becomes hysterical paroxysm when the fission levels of energy come into play.

The primitive steam based engine was discovered by ancient Greeks and technologically they could improve upon it further. Their slave based society wasn't ready for it.

Like Greeks and steam power, today we have the primitive access to space - and surprise!, instead of actively working upon improving it, pouring all our resources into it, we're still discussing whether it has economical reasons, and like in case of Greeks, we can't find much of such economical reasons for it.

'If human thought is a growth, like all other growths, its logic is without foundation of its own, and is only the adjusting constructiveness of all other growing things. A tree cannot find out, as it were, how to blossom, until comes blossom-time. A social growth cannot find out the use of steam engines, until comes steam-engine-time.' - Charles Fort, Lo!
