I know someone (86 yeard old) that never had a computer before her mid-70s. I built her several Xubuntu machines over the years, and she manages getting online, social media, e-mail and solitaire games just fine. She didn’t need much teaching from me at all. And it goes without saying that support requests are very rare and I’ve never had to reinstall her system because of some malware ate her files.

Don’t underestimate older people.
