In my practice, I found AI are more useful in adversarial mode ("criticize this concept, "find a possible bug in this code", "challenge me", "quiz me on the knowledge"), because the knowledge found adds up to your own skills.
You don't need super big brain IQ to be creative and expressive, all you need is simply a strong opinion on something, and you don't let AI (or other people) dictate otherwise.
Now the skill issue lies in whether your opinion is a good idea or not lol.
