When the videos are completely unrelated to your search, but just happen to be new/popular videos, then yes it's useless. Surfacing relevant videos would make sense.

For example, searching for climbing comp videos and getting a completely unrelated video about some new tech gadget released within the last couple days from a random popular content creators makes no sense.

Clearly, it works for Google (content creators intentionally make click-baity thumbnails and titles because Google encourages it), but it's user hostile: it's designed to suck you into a vortex, which is not what the user was intending in the first place.

That said, all content platforms do this right now, so my intention isn't singling out Google. It's frustrating nonetheless.
