Yes, this is becoming an increasing problem.
Among my circle of friends and relations, there are a significant proportion who do not "do" all of this "online" stuff.
In our local ASDA they recently reduced the number of "manned" checkouts and increased the number of "Scan and Go" or Self Scan check-outs. We shop early (07:30) to avoid crowds, and, at that time, there is typically only one "manned" checkout operating. For several weeks there was chaos at the "automated" area, with customers unable to operate the technology.
Personally, I like the technology, and can use it, but, at 74, it does occur to me that this adaptability may not continue for ever, then what? Is it a new form of euthanasia, ie starvation because you are unable to use the latest self service till?
