The best music comes when people devote their lives to it. That's why the most intricate stuff was done in the classical and romantic periods with the likes of Berlioz and Wagner. .
I understand your point coming from your perspective, but I'm not sure that more intricate music is necessarily better music. Sometimes the more intricate it gets the more like math it gets. To me, that misses the point of music which is to express feeling, emotion or thought. Often times when it gets too intricate that is lost. Of course when the two are combined it's great, but IMO intricate does not always mean better or even good.
