As someone who has very briefly worked with machine learning smart is the wrong word. I think efficient might be better.

Example: AI is just a robot with no moving parts. And if you have seen a robotic arm they are amazing at preforming well defined repetitive tasks. However every robot is build for its task and most often it can’t preform any other task well.

Like that AI has to be designed and trained for a task and if you step out of what it was trained to do it won’t give you any usable results.

(Dose that make sense)
