Re: Sounds like...
"There is absolutely no way that any original drafters of copyright law had AI in mind"
They didn't need to, it's generic enough as it is to cover the situation.
If I have an image and put it online you can assume the right to view that photo since I placed it in a public platform to be consumed. That does not give you a licence to redistribute that photo, nor to use that photo in any of your own commercial offerings.
If I write some text and put it online you can assume the right to read that text since I placed it in a public platform to be consumed. That does not give you a licence to redistribute that text, nor to use that text in any of your own commercial offerings.
If you wish to create a textbook, that would be a commercial undertaking and you will need to seek licenses from me to include my work, whether wholly or in part. The AI organisations have such a "text book" in their possession as an offline copy of the Internet and its history, and are using it for commercial purposes right now.
If you wish to use my IP in a commercial product such as a statistical model, then again you'll need to seek a licence.
If you don't have a licence for the type of commercial usage you are carrying out then you are outside of the law and will either need to buy a licence or accept any and all legal consequences.
Pretty much all of the above was covered by the Windows 3.1 EULA back in the '90s. What's good for the goose...
