Jan Heine made a post about it recently: Technology transfer from motorbikes and cars

Bicycles are in general not all that different from 100 years ago but then again, so are most internal combustion engine cars...

If I get a new bike it will probably have disc brakes, IGH and a belt drive.

It will be interesting to see how quick release skewers will hold up to current through axle bikes seeing as it is incompatible technology.
Then again I expect places like a VO, Grand Bois and Rene Herse to keep them alive since there have been way too many really nice bikes built on that agony tech.
