Where is the limit with copyright law then? Is ChatGPT allowed to be trained on books?

If the "terms" of the book ban it, can I just read the book and then write notes which I upload to ChatGPT? (Would a Microsoft employee be paid to take classes/read books for the purpose?)

I don't think we know the answers here yet. Information wants to be free though and we're going to have to reconcile that moving forward!
