Related anecdote: A few years ago, my father bought a android tablet to my grand parents (both 85+). After watching them use it for a few minutes, I realized how user hostile the technical world has become: tons of ads popping up and asking for your attention (“click me”, “download x”, “make your device run faster”, etc).
This and apps “redesigned” every few month, breaking the workflow they've struggled to learn (they usually needed to follow the hand-written note, they had taken when I showed them how to do).
They've used it a bit more than a year, with occasional breakage, and they now have stopped completely.
