As a CS professor myself, I don't think ChatGPT really creates entirely new problems for assessment, but rather makes problems that we had been sweeping under the carpet more obvious and harder to ignore.
Any assignment that can be cheated by using ChatGPT could already be cheated before by asking a friend, an expert or paying someone else to do it.
But most teachers assumed this doesn't happen often, and thus acted as if it wasn't a thing. Making life much simpler and easier.
Facing ChatGPT will probably help us make assessment fairer in the long run (and the path is probably going to be a lot of traditional on-site assessment, abandoning the continuous assessment fad that has always been rather disastrous for equity, even if again, life is easier ignoring this).
