You missed the point about cell phones. The technology is over 60 years old, but it took FOREVER to commercialize it. The reason: telecom was controlled by monopolies, and the government owns the spectrum. In fact, the government is still wasting massive amounts of wireless spectrum-- given away free by Congress to their broadcaster crony contributors.

A lot of the problem, across the board today, is the U.S. litigation and regulatory state. So, the reality is that the cell phone revolution happened in spite of our national political leadership.
