DOES TECHNOLOGY EVOLVE? [1]

"The two legs of the Theory of Evolution that are in technology, are not at all Darwinian. They are quite different. They are that certain existing building blocks are combined and re-combined to form new building-block technologies; and every so often technologies get used to capture novel, newly discovered phenomena, and encapsulate those and get further building blocks. As with Darwin, most new technologies that come into being are only useful for their own purpose and don't form other building blocks, but occasionally some do."
