Raise your hand if you've ever ask a nephew, neighbor or colleague for help with your computer - maybe trying to change a page margin or turn off the bold setting in MS Word. That's what I thought, put your hands down. There are really a small number of "experts" like your nephew - maybe 5% of users. Everyone else just tries to get by and learn as little about technology as possible - "I don't want to study it, I just want it to work" you say - and life goes on. Now, imagine the future Internet of Things where "they" want to connect everything you own to the Internet.
"Everything" includes your washing machine, your thermostat, your blood pressure cuff, your garage door opener and your mother's heart monitor. Now imagine what happens if you really don't understand how it all works. It's one thing to have a not so pretty Word document but what if you decide when you wake up that you don't want the coffee maker to start right away and turn it off with your everpresent smartphone - but accidentally disable grannie's pacemaker. Those darned icons look a lot alike without your glasses. The bigger point is that if you think using a handful of PC programs is hard, what will it be like when dozens of other "things with computers" are "upgraded" with a host of features and commands - just like MS Office. "I need to call Philbert 'cause I can't figure out how to make toast"! I'll continue this topic next month with "Because we can - the curse of modern software".
