It is obvious that many posters on this thread haven't come across anyone in the early stages of dementia.
My mum has been a Luddite as long as I have known her. She has a fear of electricity that is completely neurotic. She is also paranoid about scams, but if you went up to her and asked her for her bank account number using a naice, educated accent, she would hand it over immediately and than ask if there was anything else she could help the thief with. Lots of fears, far too much confidence in the well spoken stranger, and too much confidence in her ability to fend off a gang of junkies who wanted her cash - it's a huge problem and has been for decades. She is 88 and up until a few years ago used to put wads of cash in her handbag and hike into town on the bus to pay her gas and electricity bills.
Dsis and I persuaded her to get a debit card and to do direct debit payments. But we've tried for decades to get her to learn to use a smartphone, to no avail. Texting and taking photos and email were completely impossible for her. She talks admiringly of her brothers and sisters (all over 80 now, and one is over 90) who are all well able and willing to use tech to enhance their lives and those of their children. Her insistence that none of that is for her means she can't easily keep in touch with her grandchildren who live in the US. This saddens us all, but while sad about it, she won't try to solve the problem.
It's not just a question of enabling more frequent contact either - Dsis and I use WhatsApp and DM could too, for the price of her monthly (very basic mobile phone) plan, but no, she has her old familiar landline, and calls from mobile phones in the US to landlines abroad can be pricey or out and out impossible, depending on plan. My phone doesn't call outside of the US, Canada, or Mexico. I can use WhatsApp to call anywhere in the world. To call DM I have to keep a landline ($30 per month just for the line) and on top of that I pay for CelticTel minutes because international calls would cost a lot on top of the monthly service charge. I could get an international option on my mobile but that would cost me more than the landline I am forced to keep.
We are all paying in various ways to try to keep in touch (Dsis bought her mobile phone and pays for her plan) and paying with lack of a close relationship because she has opted for limiting family relationships with her by her refusal to engage with technology.
For many years she has been incredulous that I can look up houses for sale in her neighbourhood, sitting here in my sitting room in the American midwest. It blows her mind. Dsis was able to order grocery deliveries for her during covid, and looked up solutions to her TV remote control problems for her. I have looked up various tradespeople for her, found painters, garden people, etc. She gives me family news on the phone from relatives in Australia and I already know it thanks to SM. Amazeballs! And all of this connectivity and closeness could be hers too, but no.
No, no, no, no. 'But I can't do it'.
