I think this reinforces that the effort to enforce or police the use of AI tools may be misplaced. Better use of energy to teach appropriate use.

I still think that in the future, the assumption will be that AI was used. Similar to how we don't declare that we used a word processing software now, declaring use of AI may also be unnecessary. The authors should take full responsibility for whatever it is that they submit.
