On the genuinity of hostorical book

Let's play a game:

1. Read this article: Judging a book by its genomes
2. Wait for like 1 or 2 years
3. Ana I bet that within two years they will notice the number of books that they are using as witnesses will turn out to be wrongfully dated, what do you think?

Yes of course I know that they had already dated the scripts that they will use on C isotopes and they never rely on the dates and facts provided by authors... But think about it, wouldn't it be cool :D.
