I'd make a distinction on:

-the entropy of the data: a video is orders of magnitude than browsing metadata.

- the compute required: other than an ML algorithm optimizing for engagement, there's no computationally intensive business domain work (throughput related challenges dont count)

- finally programming complexity, in terms of business domain, is not there.

I mean my main argument is that a video provider is a simple business requirement. Sure you can make something simple at huge scale and that is a challenge. Granted.
