I'm really annoyed by the recent rhetoric that AI training is the worst intellectual (property) theft in history when the enclosure of the 20th century's public domain under effectively perpetual copyright is in fact the worst such theft in history.
I'm against copyright entirely, but if it must exist then it should last at most 14 years, not a century-ish.
If we had reasonable copyright terms (even 30 years!) there would be no lack of public domain training data for AI.
