My experience mirrors yours. It's interesting to me that the details you give about being very familiar with cash handling seem to just get ignored. At one point in my life I would regularly have two or three hundred dollars in cash on my person at all times, would pay rent in cash, repeated things like 'cash is king'. Now, I haven't touched cash consistently in years. I tap a card to pay for things. It is much more convenient, no coins, no worries that I've exposed money on my person to some one who will act on that knowledge.

I dunno. Feels like an electric kettle. I didn't forget how to boil water on the stove but pressing a button is more convenient and now I cannot forget to turn a heating element off.
