What happened to Kanye's lyricism?

IMO, A lot of Kanye's Vultures verses are unlistenable, with their only saving grace being Kanye West singing them... But what happened? When recording MBDTF you had to wear a tuxedo just to get into the studio, and there was even a strict no-phone policy. In contrast, you can find Kanye recording Carnival in the middle of a party, seeming to say shit off the dome. But what happened? I go back and listen to Saint Pablo and No More Parties in LA and am upset we may never get something even close to that again. In a time where he's experienced as much as he has, we get "Is it still mink!??". Lmk with your thoughts, is it his ego? Has he just lost "it"? Lmk
