Since the vast majority of changes in the cycling industry have been incremental I can see this continuing for as long as cycling is a thing. Each person has their own threshold for upgrades. Many on this forum are still locked into old school steel bikes with tubulars, rim brakes, triple chainring etc. for others they desire the latest S Works Tarmac SL7. Now its lightweight aero climbing bikes and 13-speed clusters. 3D printing is becoming a thing, carbon still has lots of room for development and innovation as do drive trains so I don't expect the upgrade machine to ever stop.
