My mum is in her 70s and is terrified of all technology. She's never used a computer (refuses to try), she won't even use a cash machine as it's too complicated and always goes into the bank.
So she was in her 20s when cash machines first appeared in Britain?!
I don't know if it's the case for other elderly people, but I get the distinct impression with my FIL (79) that, as well as 'being too old for all of that stuff', he partly feels it would be like losing a lot of control of all that the knowledge and experience that he's built up in his life and maybe force him to accept that much of it is now effectively obsolete.
If it makes sense, I'd liken it to winning the jackpot in the lottery at the age of 80: you'd be so thrilled that your children, grandchildren, great grandchildren etc. can have secure, comfortable lives; but, whilst it was necessary for all of those years, as you can't apply your win retrospectively, in one way, it can effectively seem like, on balance, all your work was for nothing.
I think it must be very embarrassing for a lot of proud elderly folk when they have 7yo (great) grand children who can understand something perfectly that they themselves don't have the faintest clue about. Not just something 'for the young' like knowing the names of the Octonauts or lyrics to the latest pop songs, but actually, as a young child, knowing the basics of how the whole world functions better than somebody 6, 7, 8 decades older does. In those circumstances, I can well see how you would find it easier to dismiss it all as laziness, a fad, fancy bells and whistles for the sake of it etc. than to come to terms with, in some major respects, much of what you've spent your life learning and understanding is now sadly pointless.
Sorry if that comes over harsh - it really isn't meant to, and I am most definitely NOT saying that older people themselves and their lives are obsolete - couldn't be further from that; but I probably haven't explained my thought process that well.
I often think the same when you hear of people who move to another country and stay (or are forced to stay) in their own little communities, meaning that they can live for 30 or 40 years in a country - having moved there already as an adult - and then their 5yo grandchild ends up already speaking the language of the country they all live in far better than they ever will. It just seems so very sad.
