When a technique removes something from training or a model, an imperfect match between the monitor and the target can incentivize removing both the target and the ability to monitor it.

“which is if you use a technique to try and like remove something from training or from a model,”

“then unless there's a perfect match between your monitor and the thing,”

“then you're both incentivizing getting rid of the thing and getting rid of your ability to monitor the thing.”
