Nuh!  I don't reckon, we would have to teach the young how to live without 'em :^O I was in Dymocks book store in Sydney many years ago when all the lights went out and the cash registers that told the cashiers what change to give stopped running. Would you believe none of the young cashiers had any idea how to count out change? I stayed with her until the lights came back on doing it for her 😞 So yes, we'd have our uses again :^O

While we were visiting our son and DIL over Easter we got into a discussion on this topic. So my OH wrote a whole lot of numbers on a piece of paper and asked them to add them up without calculator or anything else. He did it very fast, they were still struggling after 5 mins. My OH had a basic education, these kids have 6 uni degrees between them.

Two very red faces and one smug OH.
