>And now everything is stale and the same.

This has been less true every year since Usenet and Geocities. Much of the stuff on their was pirated, but that was the "stale and same" stuff you're complaining about anyway. The rest of the stuff was all kinds of original, good and bad. There's never been more total "content" and more total variety. You just have to look around for it (but that's also never been easier).

Letting AI companies try to profit off of all that creativity forever while choking the ability of the creators to make future revenue off of it is exactly what would actually lead to a "everything is stale and the same" situation. Preserving variety and novelty of new creation would look like putting in new restrictions to reduce this not-envisioned-when-the-laws-were-made sort of read-once-slop-forever usage.
