After Katy Perry's space mission, I'm convinced that retooling the American Idol judges panel with Carrie Underwood was the right move because Katy is too busy with her other career endeavors to give her full attention to the show. When Katy decided to leave American Idol after seven seasons, she said that it was because she wanted to focus on her own music career again. She'd been on the judging panel with Lionel Richie and Luke Bryan since ABC revived the show in 2018 after its 2016 cancellation by FOX.
