No, what will happen is that sometime in the next 50 years a DMCA request will coming for removal of those films due to images or music on them. One is entitled "Rush Hour" so will probably be caught up in a sweep for copies of the Jackie Chan film of the same name. Or youtube will go out of business (like the original google video).

After about a year 10% of them will have been removed.
