> What else do you expect from a recommendation system? Predict what you're interested next or what you're going to do tomorrow?
Actually, I think they kind of are trying to do this (in a sense), if you read the article:
> Our system then compares your viewing habits with those that are similar to you and uses that information to suggest other content you may want to watch. So if you like tennis videos and our system notices that others who like the same tennis videos as you also enjoy jazz videos, you may be recommended jazz videos, even if you’ve never watched a single one before.
