All technology is like that. When it is new change happens very fast and then as in matures the rate of change becomes slower. An example is airplanes. We know what a Write Flyer looked like on 1905 but by 1915 the planes used in world war I were much different and by the 1930, another 15 years we have some aluminum mono planes and by 1945 we had the P51 Mustang and the Germans had an experimental jet fighter. But today when a new airliner comes out (say the 777) it looks a lot like the old one. What happens is that engineers think of the easy and obvious improvements first and then as time goes by only incremental changes are left. Other times change is limited by economics. The more complex device requires more engineering time and more expensive factory equipment but it would raise the price above what the market wants to pay. So the product is kind of stuck. Tractors are that way, we can add electronic controls but the basic design is very stable now. Machine tool mechanics and servo motors are what I'd call very mature technology and I'd not expect rapid change.
