Well, those who don't like or don't want electronic shifting should have at least 30 years to get used to the idea before being forced to use it, and quite possibly not even then. Technology from the 1980's (6-speed freewheels, downtube friction shifting, lugged steel frames, etc.) is still readily available to anyone who wants to use it.

Agree it's progress or lament the change? Either way you can have what you want.
