As nice as this would be, it's not very likely... Licenses are usually limp suggestions from the perspective of companies with billions of dollars. AI companies train on millions of copyrighted materials, both literature and art, without any express permission from the authors or artists, and with essentially no recourse or compensation to the authors. You could append a 'no AI training' clause to an existing license like the MIT license, but the impact that will have will mostly be brief personal satisfaction and won't change what the AI companies do. It's genuinely more useful to keep code proprietary to prevent it from being used to train AI models.
