It’s Solow’s paradox: “You can see the computer age everywhere, except in productivity statistics.” — Nobel Prize-winning American economist Robert Solow, in 1987

I forget where I heard this but there was an interesting quote:

"In the early 1900s, 25% of the US population worked in agriculture.

Today it's 2%.

I would imagine that economists back then would be astounded by that change.

I should point out: there were also no pediatric oncologists back then."

Your dad sounds like a wise man!
