Fewer people would create scientific or artistic works if they could just be copied or used without protection either; or so is the premise behind copyright and intellectual property; even being deeply embedded into the US Constitution (Art 1, Sec 8, Clause 8).
I agree. Some existing licenses don't seem compatible with AI training. If they don't go back to rectify that, at the very least you should be able to license your work in a way that explicitly prohibits AI training. They can pay if they want to use it.
There is sooo much irony here.
