I think it's more that technologists tend to underestimate the social factors, edge cases, general "stickiness" of this stuff. We see the destination and think "ah, well the technical problems have been solved, we can all start using the new thing right now and it's clearly superior, as everyone can see, so surely that will happen very quickly" When in reality there's, - People who aren't convinced yet - People who don't want to be convinced (because of comfort, hubris, or livelihood) - Human processes and skills that have to be adapted to a new way of doing things - Material cost of making those transitions, which has to be justified to those making decisions - Ecosystem support Etc etc
