Nobel prize winner in economics Robert Vogel says.....

Vogel says lots of interesting stuff in this interview. For example, he discusses why

it took 4000 years to go from the invention of the plow to figuring out how
to hitch a plow up to a horse. And it took 65 years to go from the first flight
in a heavier-than-air machine to landing a man on the moon. Not only did that
happen in such a short period of time, but over a billion people all over the
world watched it happen.
