I agree with the sentiment that humans keep moving the goal posts with the definition of ‘intelligence’.
Your definition however of relating it to ‘goals’, appears to redirect the definition to another word. Now you have to defined the kinds of goals that reflects intelligence. Can you define that set of goals that appears in your definition to require some kind of learning?
I don’t think I can give you a pass for defining something using something else that you have not defined well enough. Sorry!
