The ability to train generative AI to impersonate humans is an example of something that can be done now because of new technology but which perhaps should never be done.
I watched part of a video that is allegedly a lecture by Richard Feynman on why it will be impossible for explorers to Mars to return to Earth. In fact, there are many of these fake Feynman lectures on YouTube. They apparently do identify in the first seconds that they are an AI generated voice or graphic. They also match Feynman’s spoken delivery style, his turns of phrase and lecture pacing. I now appreciate the problem in textual forensics that confronted medieval scholars when they sorted out Pseudo-Aristotle and Pseudo-Dionysius.

The creation of these fake videos creates an intentional falsehood which by its nature will replicate both itself particularly and others in general by creating an ecosystem that supports those lifeforms. Based on what I know about the evolution of life on Earth, I can only say that while some generative AI may be beneficial and others neutral, the impersonation of real humans is toxic. Videos from writers using generative AI will thrive creating and nourishing populations of pseudographia. It is inevitable that students who want to learn from The Feynman Lectures on Physics will land on one of these pseudo-Feynman lectures.

It is also true that each of us is responsible for determining the truth or falsehood of any assertion, even of our own assumptions. I never saw a P. F. Chang’s until I moved to Austin in 2011. I thought that it was local. I first saw a parody of Edward Hopper’s Nighthawks as a hip or campy wall poster back in the late 1960s before I learned the original in an art history class at Case-Western Reserve University in the summer of 1969. The first YouTube video I saw was Weird Al Yankovic’s “White and Nerdy” in 2005. A classmate in a criminal justice class at Washtenaw Community College showed it to me and I really identified with it. The kids in the class explained the other half of it.

I enjoy surfing YouTube videos because I like to admire the creative works of others and I learn a lot from them. Looking for printing and typography, I found Elle Cordova’s “Fonts Hanging Out” and “Punctuation Marks Hanging Out.” I also watch Mathologer and Numberphile and I have been going to sleep with David Miller’s series, Quantum Mechanics for Scientists and Engineers in my earphones. (I am testing hypnopedia. I will post here when I can speak the vocabulary.) I also subscribe to Rob Words, Audiomachine, and Microbe Hunter, as well as Jordan B. Peterson and Dwarkesh Patel interviewing Sarah Paine, among a dozen others.
A friend who got tired of the AI-created misrepresentations of historical fact warned me about YouTube. Now I understand.
Granted the warning, these simulacrae could prove valuable. Perhaps we cannot have too many copies or reconstructions. Civilization is fragile and literacy is even more delicate.
Aristotle’s own library was regarded as a royal treasure by the Macedonian ruling family. When they fell out amongst themselves, the scrolls were buried to keep them from competing claimants to the throne. When they were recovered, they were found to have been eaten through. Later scholars reconstructed them, but not well. Fortunately, those were not the only copies; Christian monasteries had preserved others. The Renaissance began when Petrarch and Dante visited those scriptoria to recover the lost writings of antiquity. However, they started with Latin, which they could read. Greek texts did not reblossom until the Renaissance took root in Venice, where Greek was known. Since then, scholars have improved the correctness of our reconstructions. In addition, other works have been unearthed. Aristotle’s lecture “On the Athenian Constitution” was rediscovered among the Oxyrhyncus Papyri. Similarly, in our time The Archimedes Palimpsest was recovered and lately one more page was found astray. But all of that only provides more evidence about what we know to be a huge body of lost works. “Oxyrhynchus yielded a huge random mass of everyday papers — private letters and shopping lists, tax returns and government circulars ... maybe 50,000 in all.” — https://oxyrhynchus.web.ox.ac.uk/waste-paper-city The Archimedes Palimpsest is another recovery with story of several losses and rescues**.
(https://archimedespalimpsest.org/). So, these AI simulations could prove valuable.
The reason that I listen to Prof. David A. B. Miller’s lectures on quantum mechanics is that I found the textbook in the stacks at the Kuehn Math, Physics, and Astronomy Library when I was working at the University of Texas. It was perfect for me, a good midrange guide for college sophomores with clear narratives that are integrated with the relevant and necessary mathematics and instructive problems. I looked for a video and found the series.

On that basis, imagine that some catastrophe has erased much of our collective electronic memory. Disastrous as the losses would be, they could not be complete. A later generation could scan the books and other printed media and also use AI to rebuild the videos from fragments. The future could enjoy reconstructions of significant portions of our achievements while inevitably deploring the losses which they know only from inferences.
** On 6 March 2026, the Zeitschrift für Papyrologie und Epigraphik reported the discovery of a lost page of the manuscript, now held by the Musée des Beaux-Arts de Blois. The text corresponds to page 123 of the Palimpset's version of the On The Sphere and Cylinder, Book 1, Proposition 39-41. The reverse depicts a painting of Daniel surrounded by two lions.— https://en.wikipedia.org/wiki/Archimedes_Palimpsest
