Are we living in the Matrix?!

When historical documents were examined using tools for detecting AI-generated text, the results were astonishing.

When the U.S. Declaration of Independence was uploaded to an AI detector, it thought for a moment and then delivered its verdict: with 99.99% probability, this text was generated by a neural network!

So does that mean that two hundred years ago the Founding Fathers decided not to bother much and asked ChatGPT to write the Declaration for them?
