Artificial intelligence really isn't that smart yet. People are still working on how to train machines and how to make AI technology easier for the average programmer to use.
Today's robots still can't do things like climb stairs very well, balance when picking up heavy objects or grasp tiny or odd shaped items.
But some of the smartest people in the world are working on making self-learning robots and other machines. It is all definitely coming and Amazon is already using this tech in its warehouse and delivery operations.
