There are still major changes coming. Youtube will need to institute two changes. First, they will need to allow content creators the ability to designate kids content instead of relying on an algorithm. Second, they will need to create an age wall for all viewers not logged into a youtube account. They will have to treat kids content completely separate from regular content. Youtube will need to move away from algorithms for kids content and use more manual review. This means only a handful of channels can survive. Youtube knows the best indicator of future behavior is past behavior.
