The only remotely credible position I’ve heard is “because humans are special, and AI is just a machine”, which is a doctrine but not an argument.
This whole discussion would have been incomprehensible any time before 1700 or so, when the idea that creators had exclusive rights to their work first appeared.
Somehow, human culture survived thousands of years when people just made things, copied things, iterated on others’ ideas. And now many of the same people who decried perpetual copyright are somehow railing against a frequently-transformative use.
IP should either exist for everyone (which would cripple LLM providers) or no one, in which case the Pirate Bay and shadow libraries should be fully open.
To be fair there is also value (at least for now) in sites that aggregate quality content and republish as a secondary level of discovery if my agents don't go far enough down the search results, but I'd expect that value to diminish over time as I better tune my research and build my lists of originating authors.
And to be clear, I don't like the idea of people stealing someone elses content and republishing without attribution (although it has been going on long before ChatGPT) but I think now we can all run agentic research teams the "bad actors" will slowly get filtered out of the ecosystem.
We also have societal norms around plagiarism.
Additionally, the claim that because people have the right to do something then we should extend that right to machines is strong. (And one I certainly reject).
