If you think about it, the changes in the models working off data from the internet would actually make the unchanging defensive model (and to be clear it’s wrong to think that the AI based Defensive model would be static either) would make the defensive model more accurate over time because the less than 99% accurate generating models would eventually feed back into themselves dropping efficiency over time. This is especially true when models are allowed to learn and grow off of user prompts because users are likely to resubmit the results or make generative API Requests in repeating sequence to make shifting visuals for use in things like song visualisers or short video clips.
