Exactly. It would be great if you could explain it to me. Okay, so it's super simplified; actually only for one user. data is used and collected by, I don't know, cookies or whatever and then there's an algorithm that evaluates it, my data and then gives me personalized information or, yes, not only offers, but sorted everything I'm looking for and so on. Okay. Such a cycle that takes place once. Super, then generally asked: How did you learn something about how algorithms work? I don't know. Difficult. At some point on news and sharing with friends and acquaintances. can you remember concretely any messages, even topics, where you have exchanged with your acquaintances or friends? Not to a specific situation. That is rather a general knowledge, which buzzes around in my head, but I do not know exactly, when and where I acquired it. Okay. Yes.
