LLMs also do not have anything like memory, by design. Everything bolted on that smells like memory or is being called memory is a crutch, at best. Not being pedantic, I just think this aspect is lost on a lot of people.
In other words, there's a story-document between a SherlockHolmesBot and UserPlaceholder that's growing like a crystal formation. Some software sees "Sherlock Homes Says" and then "performs" the dialogue at us, and we then assume Sherlock Holmes exists with a mind and memory, rather than being a facet of a text-story.
