Copyright, as defined in the U.S. Constitution, exists "to promote the Progress of Science and useful Arts"[1]. I can think of no better modern example of "the Progress of Science and useful Arts" than AI models themselves. Therefore, it follows that:
1. Existing copyright laws should _not_ be applied in such a way as to make training these models any more difficult than it already is (as that would be in direct opposition to the stated goal)
2. AI models should be copyrightable by the person training the model (for the same reason any other software program is copyrightable)
3. Output of AI models should be copyrightable by the person running the model (for the same reason any other creative work is copyrightable) provided the output does not conflict with any preexisting copyright
For those who think training on copyrighted materials should be illegal, explain to me how that helps "promote the Progress of Science and useful Arts" and I'll re-consider my position.
