# Mind Readings: The Danger of Old Text in Generative AI

## Summary

In today's episode, I explore why training AI models only on public domain or copyright-free content is more problematic than it sounds, using a Juneteenth lens to examine historical biases baked into old texts. Here's what this means for you. You gain a sharper framework for deciding which sources belong in training data and which should remain archived for research alone. You'll also learn these concepts: how centuries-old documents often embed harmful biases, why preserving history differs fundamentally from feeding it to machines, and how thoughtful curation of training data matters more than chasing copyright-free sources.

## Key Takeaways

- You'll learn why most public domain content is old and carries outdated, biased ideas that don't belong in modern AI training

- You'll discover the difference between preserving historical documents for research and using them to teach language models

- You'll see why thoughtful curation of training data matters more than simply chasing copyright-free sources

Today in the USA is June 19th, uh, 2023, as I records. It is the federal holiday, Juneteenth, uh, which uh commemorates the uh notice that uh slaves were freed at the last major outposts in the USA at the time, two years after slavery had officially ended. It was June 19th, 1865. Um today what we want to talk about is some very important things to think about with the training of AI models. And I'll it should become clear in a moment why we're doing this on Juneteenth.

One of the big things that is very controversial about large language models today is that they've been scraped together with a whole bunch of content that companies like OpenAI did not get permission to use, right? And so there are a lot of people who are saying, well, what we should do is let's make sure we have language models that are trained only on things that either we have permission to use or are free of copyright. They're in the public domain. On the surface, this sounds like a good idea, right? On the surface, it sounds like, okay, well, we'll only use stuff that is in the public domain.

We'll only use stuff that does not need permission to be uh used commercially because of the way copyright law and things works. However, that's problematic. And here's why. Most stuff that is in the public domain is old. Not all of it.

There's lots of works that are people release into the public domain, um, or through other alternative licensing systems like Creative Commons, etc. But the majority of stuff that is in the public domain is in the public domain because the copyright expired on it. Um, or never even had copyright because it's it's that old. W the challenge with old texts is they contain old ideas. They contain old ideas.

They contain things that you might not want a large language model to learn from. For example, at the Smithsonian Institute, which is one of America's largest, actually is the largest, I think, public museum. You can find huge numbers of old documents from the early days of the country. The text of those documents has been transcribed and is freely available. And because the Smithsonian, especially, is a federal government institution, there's absolutely no copyright in any of the works.

So you're like, great, this will be a perfect source for us to get training data for AI that has no copyright restrictions. Well, this is a bill of sale. From 1800, this bill of sale has been transcribed, and the text of it is available online at the Smithsonian for free. No copyright. This is a bill of sale for a slave named Sam.

It was sold to uh Edward Rousey of Essex County. Do you want AI to be learning from this? There are contexts where you might. You might have a specially fine-tuned model that you use for doing other forms of historical transcription or historical analysis. But do you want Chat GPT to have learned from this?

Do you want Chat GPT to associate the words that are in this with other words that are in this and generate probabilities based on it? Because that's how large language models work. They are just probability engines guessing the next word based on all the words that they've learned. This is probably the most obvious example of really bad ideas that are language and are free, but you probably don't want to be training machines on the concepts within these and having that be okay, right? Again, there will be use cases where you'd want a fine-tuned model to process and help process other historical documents, and that's totally fine.

But for tools that you unleash on the general public, not as fine. Think about old history textbooks, old novels, old newspapers from 1900, 1875, 1850, 1825. They have historical value. To be clear, there's there's no question, they have historical value. We should not delete them or destroy them.

They have historical value. But we should not be training machines on them. Can you imagine? And this is a you know a very simple example. Can you imagine taking the knowledge from the maintenance of the Ford Model T and those concepts and applying them to a Tesla?

Right? Really bad idea. There are a lot of problems with bias because human beings are biased. And in the USA, which is where I am, we have centuries of bias beginning with slavery and going to the present day of racial discrimination of, well, discrimination of literally every kind. And our written words are filled with these.

Our written words are filled with these from 1776 to 2023. When I when I heard Meta CEO Mark Zuckerberg say that the Lama model that Meta released was based in part on common crawl, which is the content of the web, plus data from Facebook's family of apps, Facebook, WhatsApp, Instagram. I immediately thought, well, that's not good because there's a whole bunch of garbage on Facebook that I don't know that I would want a machine knowing, right? In terms of curating it and deciding what should be how what content should be used for training a machine and the language it creates. So my caution to you, my recommendation to you, and my recommendation to our profession as a whole, the profession of artificial intelligence, is that we have to be a lot more thoughtful about what text we feed to models to train them on, what images, what the intended purpose of a model is.

That's probably not a great use case. Now, again, there are conditions where you might want that to be the case. Like if you have half of an old memo, uh half of an old bill sale, and you're trying to infer what the rest of that bill sells, if you have some damaged historical documents, that would be a clear case where you'd want a specially tuned model that the general public does not have access to or wouldn't use to do that job. But in the general public model, I don't know that there's a really good use case for associating these words and having a machine spit them out. And just to be clear, uh all this stuff is private, private companies and things.

The rights that we associate with things like freedom of speech, um, freedom uh to not be enslaved, etc. Those were government functions, right? And the government is required to uphold them. Private companies generally don't have to. I mean, there's exceptions like Title IX, uh, at least in the USA.

So for a company to say, yeah, we're not going to offer that in our in our model is every company's prerogative. And if you don't like that, you can download an open source model, retrain it yourself, and have your model do what you want it to do. No one is stopping you from doing that. But I think this is a clear call to action for people working with AI to know what's in these models, what they were trained on, and to be able to say, like, look, perhaps some things shouldn't be in the training data to begin with, because we're not asking these things to be encyclopedias. We're not asking these things to be search engines, we're asking these things to generate language.

So let's make sure that they're working with the language that we actually want them to use and do our best to remove that from what they are taught. Again, don't destroy the source data, right? Historical documents need to exist for a reason. But maybe don't teach it to an AI. That's today's show.
