It must be 20 years ago that I was doing outreach work in the local libraries - teaching the 'oldies' how to use a mouse and keyboard, email and internet - along with photo editing/storage and genealogy. They did well, as they were the ones keen to master it. What happened to the others who never did use IT? They must have been dependent on others for help.
Even then, we knew they'd soon have trouble (or be lost) in everyday life without it - and, of course, it constantly changes and updates, needing regular 'new' hardware and software - often at a cost (or gifts from their children of 'not quite the latest' phones and laptops).
A couple of years after the classes stopped, one ancient chap tracked me down at the college - because he was 'stuck' with booking a holiday online!
Is it rude to not finish a book club choice that was selected by someone else?
