I think it's a pipe dream to imagine that all future interactions will be through mobile devices like phones. The way I see it mobile is adding extra time spent with tech instead of replacing desktop entirely. People spend more time online then they used to, a lot of it due to mobile devices becoming common place. Some time that used to be spent on desktop is migrating but not all of it. Desktop and Laptops will be a thing for a long time.

Another thing I find annoying is we went from mobile first to mobile only for a lot of things. The point of mobile first was to ensure that the less capable devices were not second rate citizens to desktop. Not that they are the only thing customers will use to access services.
