The logic that says that we shouldn't insist on the use of technology because some people 'can't' engage with it is similar to saying that we shouldn't have telephone helplines as not everyone has a phone. There was a time when that was true, but sooner or later it was expected that people would catch up and get one, or borrow the use of one. Should we stop having public service announcements on TV in case those without one miss out? I think that this is the same in many ways.
There have been dual options for ancient twits for years - there is an argument (which I am not necessarily making) for saying that all but the most ancient or twitesque could have made the effort by now. Everyone on here is IT literate enough to post, and has access to something from which to do so, and there is a wide range of ages on here.
OTOH there are people like my MIL who is nearly 100 and has never used a computer in her life. There would be no point in giving her a QR code - apart from anything else she doesn't have a gadget that could read one, even if she knew what one was. The trouble is knowing at what point to set the cut-off, to encourage everyone to at least try to get on board. By then there will be other things (AI?) that will have come on stream, so I suppose society is always playing catch up.
It is an awkward question but I did feel a bit like that advert with the man trying to buy some veg but he could only pay with crypto when I was trying to take GC into soft play and I couldn't pay with money or a debit card or online because if I paid online I then had to scan the QR code.
I was saved by the helpful young man on reception who took my money, booked me in on his phone and scanned the QR code for me.
My issue isn't that I can't use tech it is that I need to spend money on a new phone when I have one that does everything else that I need.
