There are old people who might never use it. That said, my 70 year old parents use it sometimes.

My bubble is working adults, which is likely more represented by the 58% under 30 figure. However, this was a year ago. I'm guessing adoption has accelerated even more in a year. It wouldn't surprise me if it's 50% overall by now and 70-80% of adults under 30.

So these facts don't actually dispel my intuition.
