There is a case to be made that it will happen much faster than we play out still though. We're thinking linearly, based on past history, but the rate of change is growing exponentially.

Shopping online definitely took longer since it required people to also adopt the internet first and foremost. Word got around much more slowly prior to the internet.

Bitcoin on the other hand already benefits from having a speed-of-light communication network up and running, and adoption is thus taking place much faster

Hard to tell how quickly/slowly things will actually speed up. With AI entering the equation too, I think we underestimate how much impact that will have in driving new tech adoption
