or by replying you expose yourself to handing -proof- of the origins of the training data set to the copyright owner wanting to sue you next

Well presumably since they're individuals and not a business the consequences are much less severe legally - but public opinion still won't be great, but since when was it ever, for any new thing?

If I cut up a song or TV show & put it on Youtube (and screech about fair use/parody law) then that's fine, but people will balk at something like this.

AI is here, people.

No. It's for giving credit where credit is due. And yes, that includes the question if the people who generated the training data in the first place have given their consent that this can be used for AI training.

It's quite concerning that the community around here is usually livid about FOSS license violations, which typically use copyright law as leverage, but somehow is perfectly OK with training models on copyrighted work and just labels that as "fair use".
