I’d think, in this case, you’d still have to legally acquire the content. So meta pirating a ton of books would still be piracy, the act of piracy would be illegal. Scraping the entire internet for publicly posted data isn’t illegal, however, so that’s still “fair game”. Of course, the internet is full of illegally posted content, so I’m not sure how you account for all that when training AI (most model makers probably don’t bother to try). “Sure, we trained our model on Disney movies, but user FartFace6969 posted them to youtube mirrored with the audio pitched up, your honor!”
I’ll add my experience to it as well.
I recently used it for a trip. I put into it my flights, hotels, checking/out times, reservations, and any other pertinant travel data. It gave me one single place to find a rather large amount of data.
It also helped me keep my timelines straight as I was booking things to make sure I didn’t have any overlap.
