In a more free perspective, artificial means man-made. The strict technological definition for AI is a limited one, however, people can talk about it in philosophical terms as a simple man-made definition. It being artificial can simply mean that man created the ancestor robot, but (I don't know how) its byproducts or new version created itself to become a truly intelligent being.Artificial intelligence isn't true intelligence for it is only a bunch of numbers interacting with each other. It isnt thinking at all, its programing is just interacting.
This is just interpretation of the word, though.
How about those androids and cyborgs?
