I think GPT4 isn't amazing (that is, better than excellent humans) at any specific task, so I doubt that many things it does, in isolation, are remarkable. Where they shine is that GPT4 and ChatGPT are really good at doing lots of menial tasks really quickly. e.g. I can ask it to refactor my code, rewrite it in a different style, add a new function etc and it'll happily do that all day.
Probably the best use case was for learning about things I didn't understand. I asked GPT4 questions about CSS Grid yesterday. With GPT4 I could drill directly into areas I was curious about and get a pretty uniformly good explanation, e.g. "explain to me more about the layout algorithm". Doing that with google is possible, but it's annoying to have to continually bounce between various shoddy articles on different websites in order to get a patchwork of understanding.
