"The poster seemed to be suggesting that anyone over 50 is less likely to have been exposed to IT technology - not that their age made them less competent generally. That seems reasonable."
Even if we disregard earlier stuff such as the Apple II, Trash-80 etc, someone aged 50 this year would have been ~14 when the IBM PC was introduced. And I know people born in the '20s & '30s who can find their way round PCs (and have worked out how to download Open- or LibreOffice because that's what they use).
" I remember people of my parents' generation born round the start of the 20th century who had never adjusted to an understanding of electricity or radio."
That would be the same as the older members of my parents' generation. I never met any of my aunts, uncles or their friends who had the slightest unfamiliarity with either.
