Long-term memories on the other hand are at the core of the purpose of CSML. When two persons converse, they constantly memorize information, which they can reuse in other discussions. For example, if I gathered that my friend likes Iron Man, I might propose later that we go see Captain America together. I do not have to ask them again about their favorite film, because I already learned this information before, even if it was in a different conversation, even if the topic of that conversation might have been completely unrelated.
