So sometimes when I want to hear what my song COULD be if I were good at every one of those, I will use Suno. But I do not let it change my lyrics, or chose it's own arrangement. I will give it a VERY ROUGH demo (out of key singing, basic drums and strums, and it will "polish" my turds into really shiny turds.
The problem being that the users of LLMs aren't even putting forth the effort to do the stealing themselves, which would at least have implied some level of discernment and artistic effort in selecting what to steal.
Like bad managers stealing credit for their subordinates' hard work, bad LLM advocates wish to normalize taking credit for the work the LLM does on their behalf.
