How will we know that we are reading something authentic written by the original author vs something that has been altered and rewritten? This may have been a problem in the pre-AI world as well, but with the ease one can generate text now I wonder if there is a much greater risk.
Sure—the point I was trying to make is that it still needs to be done piecemeal, while a blockchain can verify a collection of works as a collection (that is, it not only verifies that each work is unaltered, it verifies it in the context of other related works).
