> The issue is using copyrighted content without consent
the consent is given implicitly if the content is available to the public for viewing. The copyright isn't being violated by an ai training model, as it isn't copied. The information contained within the works is not what's being copyrighted - it's the expression.
If the ai training algorithm is capable of extracting the information out of the works, and use it in another environment as part of some other works, you cannot claim copyright over such information.
This applies to style, patterns and other abstract information that could be extracted from works. It's as if a chef, upon reading many recipe books, produces a new recipe book (that contains information extracted from them) - the original creators of those recipe books cannot claim said chef had violated any copyright.
