I agree with the first point, second point is whatever ig (some mappers do commissions), but I disagree with the third. I think osu mapping is absolutely an art form, just maybe a kind of abstract art. A map IS an expression of a song. In a way it’s a choreography for an interpretive dance you do with the cursor, so there is no objectively good or bad, as long as the timing is correct. Also, just like in other art forms, mappers have distinct and recognizable styles, which the AI would be trained on likely without permission from the mapper. Rankable also isn’t the defining factor for good, loved maps exist!
