LLM based autonomous agents remind me a lot of Leonard from the movie Memento. In the movie, Leonard is trying desperately to find the murderer of his wife, but he has one big problem - he can no longer build new memories. So, he needs to develop a system for storing new knowledge and then retrieving the relevant bits every time he formulates a plan for what to do next. Throughput the movie, Leonard makes a number of missteps because his system for recording and retrieving knowledge from this external memory system is imperfect. The movie is very well done.
