This is indeed true. But a challenge is that few professors are being given the time and training to help do this. When you are on a 4/4 and just keeping your head above water you don't tend to have enough time to adopt experimental pedagogies and completely replan your courses. And professors are largely being tasked with doing this independently rather than having universities offer training or support with adjusting methods to be more AI resistant. And unfortunately the fast speed of development of these tools is making good ideas obsolete quickly. I know some people who switch to having students make podcasts rather than writing papers as a final assignment and then we started seeing "create your own podcast" tools appear and made it roughly as easy to cheat on this assignment as a traditional paper.
