The worst casualty of the current design is the search. You get three videos before it inserts completely irrelevant and unrelated algorithmic recommendations. No? Fuck off? Do what I tell you to do!
But you can use Gemini for better search, recommendations and you can play videos right in the chat window. At the very least replace search and recommendations with the model. You can explain what you want to explore and guide the recommender much better than on YT. There are no ads in Gemini itself.
