Lots of us enjoy playing an instrument, improvising, etc. Even if an AI can do it better, I don't care, because just listening is not the same experience.
This was not meant to be a statement about people who enjoy making music but that in general people don't suddenly become more willing to make their own music just because there is an AI tool for it.
It still takes the will and desire to do it even if the barrier is so low as it is now.
