It just seems to me like following a rich person around hoping some coins will fall out of their pocket. It's a parasitic ecosystem that encourages content to focus more and more on "what works" in the self-perpetuating context of that ecosystem, and less and less on making contact with any kind of external reality.
These people are the best positioned to figure this out. They've been experimenting with youtube changes for years and they already know how to experiment out the particularities.
