My thoughts exactly. And even if there is some need to use the LLM for something sensitive, most platforms have some sort of incognito mode. Not that it's going to stop the government, etc. from accessing the chat, but useful for the same things you would use a browser's incognito mode for: something you don't want accessible with a basic history search
1) enable memory, and use ChatGPT like a confessional booth. Flood it with all of your deepest, darkest humiliations going all the way back to childhood ...
2) disable memory
Perhaps my age is showing. But memory or no memory, I would never tell ChatGPT anything compromising about myself. Nor would I tweet such things, write them in an email, or put them into a Slack message. This is just basic digital hygiene.
I've noticed a lot of people treat ChatGPT like a close confidant, which I find pretty interesting. Particularly the younger folks. I understand the allure – LLMs are the "friend" that never gets bored of listening, never judges you, and always says the right thing. Because of this people end up sharing even MORE than they would to their closest human friends.
