This is a good debate about copyright/ownership. On one hand, yes, the authors works went into 'training' the AI..but we would need a scale to then grade how well a source piece is good at being absorbed by the AI's learning. for example. did the AI learn more from the MAD magazine i just fed it or did it learn more from Moby Dick? who gets to determine that grading system. Sadly musicians know this struggle. there are just so many notes and so many words. eventually overlap and similiarities occur. but did that musician steal a riff or did both musicians come to a similar riff seperately? Authors dont own words or letters so a computer that just copies those words and then uses an algo to write up something else is no more different than you or i being influenced by our favorite heroes or i formation we have been given. do i pay the author for reading his book? or do i just pay the store to buy it?
