Funny that you mention this. The other day I thought, "Wow, I haven't messed around with ChatGPT for awhile", and I excitedly loaded it up. Then I got there and realized I had nothing really to ask it, and it just seemed kinda boring.
The fact that it only had info through January 2022 was also annoying, as this made it impossible to ask it about any current or semi-current events.
You're right that there hasn't been significant advances. It's still making mistakes, and still doesn't have a lot of practical uses outside of cheating on term papers.
