Memory in general Chat apps is actually more harmful than helpful imo. It biases the LLM responses to your background which has the same effect as filter bubbles. You end up getting your own thoughts spit back at you.

Of course sometimes this is useful if you only use your chatbot to ask personal things like: "What should I eat today?".

But if you use it for anything else you're much better off having full control over the prompt. I can always say: "Hey btw I am german and heavily anti surveillance, what should I know about the recent anthropic DoW situation?" but with memory I lose the option of leaving out that first part.
