OK, but what is your concern about having your content catered to your likes? For example, I can use YouTube and incognito mode where I just get the most popular videos, but that would be terrible because I don’t like most of those. I watch it in my account so it knows what I like and what I watch so it caters those videos to me. I guess if I had problems with addiction, then I can say that, but for just enjoying the content having it adjusted to what you like seems better.
Again, I don’t think any of us have enough information to call this a failure. Unless you are some insider at Apple, you don’t know what happened. Tim Cook could’ve said let’s see if this is even possible. They played around with it and decided it’s not possible. I wouldn’t call that a failure. You can’t call everything that goes into R&D and doesn’t make it to a consumer device a failure. I’m sure Apple has dozens of “failures” like this that we don’t know about. The Apple car was hyped up by leakers, and that was literally it. There was no Apple car.
