This sequence of dates start with 1962, when John Licklider, a scientist at MIT wrote a memo outlining a "Galactic Network,"

Has Moore's Law been in operation for a century?
This Web address contains Chapter One of Ray Kurzweil's book In the Age of Spiritual Machines. About half way through the chapter is a
summary of Moore's Law, which describes the exponential increase in the power of computers, with a doubling every 18 months for the roughly
30 years. Several pages later Kurzweil explains that the exponential progress has actually continued for a full century and has gone through
five generations of computing: mechanical computing devices, electromechanical devices, vacuum tube computers, discrete transistor computers,
and integrated circuit computers.
