I agree that it would suck for tech non-savvy people, but at the same time the literacy of general population with any technology naturally improves as time passes. Of course, while there is still a big enough chunk of people that do need a require (or just prefer) a particular way of communicating, it should be generally available at a good-enough level of convenience. The key is of course to only start scaling it back at the appropriate time, at which there is so few people that they can be considered outliers (and I mean actual, statistical outliers, not 'whoever the government doesn't consider important enough').

But all of this is of course just like my opinion man. Just a very interesting topic to think about.
