I would say that your worldview is extremely spiritually deficient, if you do not consider that musicians and composers can achieve greatness. Music at its best is extraordinarily enriching, as beautiful and intellectually thrilling as the deepest mathematics, while also speaking to us of all the lightness and darkness of our human condition. At the lowest and most challenging times of my life, it has been music that provided solace and inspiration to find a way forward. I cannot express how impoverished my human condition would be without music.
Computers have not surpassed humans in terms of musical ability. Only someone tone-deaf, unable to let music into their heart, would say so.
(I have read articles saying that computers can now produce compositions indistinguishable from Mozart's, but the context of comparison is always on the level of silly, childlike little themes from very early Mozart pieces, more like extracts from nursery rhymes. And in terms of performance, there is nothing to rival our leading humans.)
