The scale and guaranteed perfect recall are not "only" different, they are fundamental differences. I would find it odd if someone were writing down everything I said. I already find it quite strange when I write something (on Signal or similar), and the person responds with a quote-reply of something I said years ago. "But I thought you wanted to visit Moscow?" or even "I'm sure you said you wanted to visit Moscow" are quite different from "here's the message you sent on 2019-02-05 at 14:32 telling me you wanted to visit Moscow".
