In the early-2000s "copyfight", many people theorized that the apparent support of young people for the "low-protectionist" side, or their enthusiasm for P2P file-sharing, or remixing, or fan fiction, was presaging a radical shift in copyright law once those young people grew up.
A lot of them have grown up now and that shift doesn't seem to have happened on the legal side. Maybe there are some shifts in norms (e.g. many authors and publishers used to loudly maintain that fan fiction was not a fair use, but most seem to have decided that it would be a bad idea to sue over it, and it's become more normalized overall), but not much in legislation!
So I'm not sure this outcome is in any way guaranteed.
(Larry Lessig also said that his foray into copyright activism had convinced him that campaign finance was an obstacle to having legislation reflect public opinion. Not every issue is a "campaign issue", but some issues that legislators don't directly campaign on are very important to donors. Lessig concluded that copyright was one of those.)
