As someone who is not Gen-Z and remembers what life was before the internet, I can sure say that the internet beats any library I've ever spent time in.
The volume, diversity and ease of research ... all at your fingertips.
Why would anyone want to spend time trawling obscure library database systems only to find the library doesn't stock the right books or that someone has taken it on loan for an unknown period of time ?
Or worse .... microfiche. My god how that's a hellish storage medium I will not miss !
