I remember playing around with it first and doing similar things with the openai playground. It is amusing but the novelty of this type of usage wears off quickly.
I mostly use it for programming type work now. Write a little snip of code (personal projects only) or tell me how to use a library. I also use it to teach me things. I find it incredibly useful for this.
ChatGPT is still free for me but it is glitchy at times. I would definitely pay the $20/ month one it is available in my region.
