I'm not the OP, but when you're of a certain age, you don't need citations for that. Memory serves. And my family was saying those sorts of things and teasing me about being into computers as late as the 1970's.
I can attest to the fact that people who didn't understand computers at all were questioning the value of spending time on them long after the 1970s. The issue is that there are people today who do understand quantum computing that are questioning their value and that's not a great sign.
In the 1970s both my parents were programming computers professionaly.
Computing was already a huge industry. Just IBM's revenues were in the multi billion dollar range in the 1970s. And a billion dollar in the 1970s was A LOT of money in the 1970s.
