This is the crux of the problem and why the OP makes a compelling argument.
We live in a world of "innovation" where the driving force behind it is a conglomerate of VC's whose primary concerns are their multiples and the next fund. They are people without long-term vision.
We also live in a world where political are small men and women proposing small ideas because their primary concern is the next election cycle.
What ever happen to greatness?
"We're putting a man on the moon in 10 years." "We're building a national highway system." "We're building a weapon that will end wars."
Where did the will go? Where are the cries of:
"We'll be free of fossil fuels in 10 years." "We're sending a person to Mars by 2020."
Or if you like wars on abstract combatants that never end:
"The war on ignorance"
Someone needs some vision. And right now, nobody has it.
