There's nothing in the law to support your argument either. The law however does say, very unambiguously, that copying without permission isn't allowed . There aren't exceptions for "training" just because it's superficially similar to a human activity (reading a book). A human isn't allowed to hand-copy Harry Potter. Even if they bought all the Harry Potter books.
Yes it's very different. Humans need to eat, sleep, and pay taxes. You also have to pay them competitive wages.
