I don't know about that; I'm 66 and conduct almost all business via my desktop PC. It's convenient and reduces the paper pile considerably. But I guess there would be some folks, old or young, who have yet to catch on, although they'd be a minority I would think. These days, having some form of computer (tablet, laptop, or desktop -- many people have all three or more!) and an internet connection is as important as having a telephone once was.
Speaking of telephones, today's mobile phones are pocket computers that do far more than mere telephony. These devices have the computational power of machines that 20 or 30 years ago would fill a decent sized room that had to be kept at a steady temperature and required a team of skilled personnel to run.
