Only in a paper clip factory view of the world.

Situations where the simplistic PM dashboard metrics model breaks down:

- Users watch more videos than they want because they can’t find the right ones (maybe because the dislike button was reviewed)

- The user went to complete a task, then got distracted by a bad recommendation

- The user has a gambling addiction and is being served ads for gambling content.

- The user went to learn something but was served highly engaging but false content

Viewership is one signal among many.
