but yea it's like linda/frax explained
vocaloid are voice bits and you combine them into making sentences at certain singing notes, there's nothing of AI there, it's just a "voice" pack where you can make a lyrical song
it's like having the piano keys sounds and making a song outta it. you could argue that it replaces the human talent of singing, just like rearranging the notes of a piano in a computer replaces the human talent of motor coordination for playing it though
still different talents being worked on and I dont think everyone should be skilled at everything to stand out
