My parents are more computer-literate than the average late-fifty-somethings, but they aren't HN techies by any means. Having lived with them for about a year, I'd break down their Alexa usage like this:

~90% timers

~8% weather

~2% putting items in a shopping list

And I don't recall them ever buying anything via Alexa that they wouldn't have bought on Amazon some other way.
