In fact, I believe almost EVERYTHING on the internet is automatically copyrighted, including posts on this board.
The only things not copyrighted are writings that are of a certain longer age.
The problem with this, with respects to AI, is that the copyright of this board does not preclude readers from reading the content here. Anyone can wander in, read what content is publicly available, have some experience of having read it as many times as their awareness skates across the whole of it for however long a browser will retain the text of it, and then to be done with it.
An AI does the digital equivalent of that when it does training.
However, some acts of clear piracy have been done by AI creators: book piracy and video piracy and the access of content through BitTorrent and so on.
That has been done on a massive scale, but then... I have pirated more books than I have paid for, myself.
Also, I hate to mention this, but this also doesn't prevent someone from doing all this within the bounds of copyright.
The sum total of information that is absolutely needed to train an AI to a reasonable human degree doesn't really exceed the amount of information needed to do this with a human, or at least I don't see why it would.
I have had what, maybe a few hundred thousand dollars worth in books and education? At most 500k?
A lot of my time has instead been spent playing video games, or talking here... Which as noted anyone can read the records of.
Which gets me to my point: very little of this is strictly a copyright violation in the first place.
So in an interest of not wanting to pass a law outlawing "robots" from reading or whatever, I think we shouldn't consider reading the open internet to be a crime, especially when the system has a subscription, library card, or account.
I do also think, however, that letting an AI read literally everything and anything and expecting it to be capable of "predicting" the material is a fool's errand because most books are trash, most websites are trash, most forum posts are trash, most news is trash.
Pushing an unmitigated pile of trash that deep onto any sort of entity will result in something that is very good at creating and understanding... Trash.
So of course most of it is just... Trash. Because you are what you eat. And we fed this thing mostly trash.
