I appreciate the defense of the blind downvotes, though I can't say I necessarily see how Foss search engines would even be allowed to exist in that case?
Let's advocate for no one going to prison for scraping information then. Let's pick the second one where we don't put more people into prison.
AI scraping content, the same way that search engines do, will have no impact on the copyright system.
No, this is a broader issue with copyright being a fundamentally stupid system, because it's based on creating artificial scarcity where there is no need for it.
Pirates, Search Engines, the fragmentation of streaming services, and now AI, are all just technologies that expose how dumb a system it is.
You'd probably end up back with AI at that point. A lot easier to distribute a trained model then an entire web index.
