As of late i find that all tech development follows a s curve of sorts. It starts out flat, then goes near vertical as the idea catch on and all the low handing developments are plucked and marketed. then it flattens out again as new developments becomes harder, and the market consolidates. Flight seems to have hit that second flat around the time of the Concorde and the 747. And electronics seems to be hitting it right now.
