> A human creator can just as easily lie or not fact-check all their sources

Not "as easily". A human creator can make a video without fact checking anything, but people using AI can push out thousands of bullshit videos in the same amount of time.

The human creator also actually sees the content they put into their video and can catch the most obvious errors that don't even require fact checking. Humans using AI can just keep spewing out slop as fast as possible without having any idea of what any of the videos actually contain.
