I don't think they're arguing about personal use of AI to make something silly shared between family and friends. It's when those songs you made in an instant start to flood platforms where people took weeks, months or years to release an album they crafted by traditional methods. I don't want to discredit the joy you have in making fun songs with your family. I'm curious what is also gained if you made the songs by making instruments out of strings and pans, and performing / improving your own song from scratch. I'm sure the end result is the same, lots of joy and laughs. But something is definitely lost when the slow process of humble hand made creativity is exchanged for polished instant results. But maybe instant gratification is just the new mode of consumption. Ai promises that with a "good enough" button and my fear is that it will be extended to every facet of life.

Music is not inherently time-consuming to make, people can jam out a tunes at one minute per minute and bandcamp is full of those.

Would you trade your livelihood to continue to make such music? Would you trade someone else’s livelihood?

Because ultimately that is what is being marketed/sold right.
