If you ask different people the above question, and if you vary it based on type of task, or which human, you would get different answers. But as time goes on, more and more people would become impressed with what the human can do.
I don't know when LLMs will stop progressing, but all I know is they continue to progress at what is to me a similar astounding rate as to a growing child. For me personally, I never used LLMs for anything, and since o3 and Gemini 2.5 Pro, I use them all the time for all sorts of stuff.
You may be smarter than me and still not impressed, but I'd try the latest models and play around, and if you aren't impressed yet, I'd bet money you will be within 3 years max (likely much earlier).
