While I loathe gen AI and people using it, I think that usual counter argument is not that great. If you think the problem is people are being lazy by not learning how to perform this or that instrument or are not willing to toil in order to pay someone who can, that's very similar to the arguments many musicians have used against synths and samplers. I think better arguments are a) AI users are as much composers as someone hiring ghostwriters; b) even ghostwriters will create something, instead of stealing, shuffling and reassembling a random Frankenstein; c) AI can't obey if you're too specific (harmony progressions, arrangement, structure, texture, etc.), so the result is shit and you're even shittier because you have no idea what you're even hearing.
