I believe LLMs are at the very least an under-researched technology or less charitably, an ongoing effort to strip intellectual workers of their rights and privileges.
What I am saying is the reasonable demand for attribution runs counter to the nature of these systems as we know them. There is no magical "release the attribution" button Anthropic could press if they wanted to. Unlike per-state taxes, are actual PhDs working on, at universities and private labs, because transparency has been the public number one demand since day one, and yet all that exists after 4 years of funding are only the first incomplete steps.
The most likely outcome of imposing this obligation is commercial LLM providers quickly folding, finding a loophole/displaying false attribution, or settling for notably worse performance. That is of course not counting how these companies will be on the hook for a civilizational amount of licensing fees.
(Per the DRM point, I believe we can agree the goal of simultaneously displaying a piece of media in the physical world and somehow protecting the viewer from storing it is effectively impossible, without hiring a trusted guard to hold the viewer at gunpoint if they dare touch the trusted viewing apparatus or pull out their phone, at least in its strict form)
I am personally okay with shutting down an industry that cannot legally exist in its current form, especially one so openly hostile to every field of human endeavor. But no matter your position on that, we must keep in mind no "ethical" or "legal" AI industry can exist without making either adjective meaningless.
