I think it's closer to the library example. My parents have mentioned how they had to go to a library and look for books whereas my generation can just use the internet.

Realistically my guess is that the bar for broad knowledge and ability to get to details quickly will increase. There's a lot of value in understanding multiple disciplines at a mediocre level if you can very quickly access the details when needed. Especially since learning speed tends to get slower and slower the deeper you go.

Also since every time I've needed to do something complicated, even if I knew the details it was important enough to double check my knowledge anyway.
