You can recommend just based on content. I hardly ever open the youtube homepage. And often open links in incognito mode. Still get to see all these recommendations next to a video. I don't see how you could not have a "recommendation bubble" as long as you have recommendations. Even if they were to be 100% manual it's still a bubble of some kind. Not only that, you effectively have these bubbles outside the internet too. A book will recommend further reading, friends will recommend certain things and so forth. There's no escaping it. When I go to the YouTube homepage these recommendations are absolute junk. Links friends send me are much more relevant and influential. IMO the most charitable reading of this initiative is that they believe the algorithm is somehow biased towards exposing and warming people to harmful content in an unobvious way.
