"We need most of our population working full time to keep ourselves fed because running a farm is really hard" is a technical problem, not a societal one. You can solve it with fertilizer and the cotton gin or whatever.
"There's a bunch of us now and barter isn't cutting it anymore" is a technical problem, not a societal one. You can solve it with coinage and banks or whatever.
"The internet used to be fun and useful but now it sucks" is a societal problem, not a technical one. You can't solve it with a federated twitter clone or yet another secure messaging protocol or whatever.
