I think this is missing that older people are not stupid, and they could learn how to use software if they spent the time. Many older folks used even more complicated software in the past, and then they lost the skill or didn't keep it up to date.

A lot of older people rely on yougins for tech support not because they have to, but because it's easy learned helplessness.

A large part of this is ALSO software's fault, though. Software changes too quick and for no reason. Software these days lies to users, erroding confidence.
