It is so trivial that there is no ready citation for it. If private activity substantially resembles that of local government, that too is governed by the 14th, for that reason.

Technology seems to progress and evolve faster than humans.
As humans, we require at least one generation to pass to accept any major technological revolution as evidenced by our track record with such items as the Telephone, Automobile and Electricity. One can claim the advent of the computer is such a similar revolution. Just as we take the telephone and television more or less as accepted and natural components of our technology, the coming generation is being taught to accept the computer. To them the computer screen, keyboard and storage medium are as natural to them as the telephone is to us at their age. One should also note that they too accept the telephone.
