If you own a book, it should be legal for your computer to take a picture of it. I honestly feel bad for some of these AI companies because the rules around copyright are changing just to target them. I don't owe copyright to every book I read because I may subconsciously incorporate their ideas into my future work.
So what is the right interpretation of the law with regards to how AI is using it? What better incentivizes innovation? Do we let AI companies scan everything because AI is innovative? Or do we think letting AI vacuum up creative works to then stochastically regurgitate tiny (or not so tiny) slices of them at a time will hurt innovation elsewhere?
But obviously the real answer here is money. Copyright is powerful because monied interests want it to be. Now that copyright stands in the way of monied interests for perhaps the first time, we will see how dedicated we actually were to whatever justifications we've been seeing for DRM and copyright for the last several decades.
