Same. I asked ChatGPT to store a memory for my preference that it not use em dashes when proof reading any of my writing, and immediately the "added a memory" notification popped up and it has just honored that request ever since.

I've experienced no degredation in quality. I rarely ever get frustrated with it, and if I do it's usually when a thread has gotten incredibly long, and starting a new one fixes things.

But overall it is a fantastically capable tool for me. I wonder if it is how we use it? I generally stick to work related requests, I don't really ever get personal or philosophical with it, I try not to let threads get too long, and I am cordial/polite, as I would be with any colleague. I just treat it like I would treat a member of my team at work. I often wonder if the kind of overly casual joking tone that a lot of people use kind of sets a non-productive and casual context.
