A problem I didn’t even conceive of a year ago was whether or not a book was written by a human.

This author has done nothing to deserve that scrutiny, but I can’t escape the feeling now of having to be guarded when I see a new book online with a relatively short history (spring 2026 is the earliest version of this text), as I can’t be sure it’s either “AI-enhanced” or AI-written.

I don’t like this feeling and it dampers any enthusiasm I once had for being excited about stuff like this.

That aside, if the author did write this themselves without AI, kudos to them and their acheivement!

If it makes you feel better, I've known the author personally for over ten years, and he is both a human being and an excellent teacher. I'm about as confident as I could imagine being that he wrote this book himself. (In order for this to completely reassure you, you of course have to trust me, but I thought I'd add my vote of confidence just in case it helps even a little.)

This book aside, though, the fact that writing is no longer definitive evidence of human thought is one of the things I dislike the most about the LLM era. I very much share your sadness about that.

You know this is easily verifiable right…. I just put 10 random pages into Pangram and they all came back 100% human. And now I feel bad for making an even greater proportion of comments on this thread not about graph theory.
How reliable are these test though?
Pangram is very good if you can provide enough text, in my experience.

I wouldn't use it as a 100% infallible AI detector when the stakes are high (accusing someone of cheating) but it's very good at detecting AI generated text when you can drop large sections of text into it.

My anecdotal experience has been that is is very reliable on inputs over 500 words. There are a number of third party evaluations that corroborate. Pangram is pretty easy to test for yourself if you are a skeptic.
I spot-checked a few random chapters, and it looks clearly human-written to me. But I share your general worry.
Putting aside whether or not the author used AI to write this - the concern here is that the content is accurate and correct, right? So suppose they did use AI to write it - your end goal is actually the same - you want a trustworthy, accurate, source of information.

In this sense AI does not actually detract from that - so long as there IS an author associated to the book, that author can build a reputation for thoroughly reviewed and high quality textbooks. So in the end, some authors will be known for a reputation for making good books, and the use of AI should give us access to a larger quantity of books, addressing more and more niche topics, for lower costs. So, this should be a good thing for education?

I'm very much just writing my thoughts down, but curious to know if others agree or disagree with this.

The author seems to have published math papers (as one can see on DBLP and other websites) and a PhD in maths. It gives me confidence that it's written by a human and also reading chapter 1 and chapter 2 I think there is a human behind it, not an LLM.
AI tech is hitting our lives harder and faster than any tech before, and this has social and psychological side effects. society at large will struggle to recognize this, much less find healthy andeffective ways to adapt.

the erosion of trust will be socially catastrophic.

remember a time where you might admire a photo not just for its beauty, but for the good luck and skill of the photographer who captured it?

photoshop made us skeptical about truth, but AI will simply make it hopeless to ascertain truth.

note that i use AI extensively. i am hyper aware of the way it has impacted me, my peers, and my career, and im deeply concerned about how it will impact everyone as it is increasingly made "non-optional" by the rich and greedy who stand to benefit most from it.

I get your sentiment, though the problem is older than AI, the convenience and market penetration has just ramped up the visibility in this arena.

Many books pre-ai were garbage but not at the rate they could be today. If anything people operate on greater discretion now than in the past because even the worst garbage still had a non-trivial barrier to entry, either sitting down to regurgitate your own garbage or paying someone to make some garbage for you.

There's also some historic precedence of this, the rise of Photoshop/CG and digital manipulation certainly led to a "is this photo real" to similar effect despite manipulations going back to the origins of photography. That acute concern was not as prevalent in my mind before editing became common and accessible.

I'm two chapters in now and if AI wrote this well we'd be much less pissed off about it.
While the author and book here seem trustworthy, the issue is real and likely more upon all of us. Nothing that we output will escape the same scrutiny, at least for a while until we will probably have own dedicated AI to scrutinize everything that gets in front of us
Perhaps we’ll reach a point where humans might have to record themselves writing the things and publish this next to the work itself to prove it was human made.
I have just taken this in stride but it has struck me a few times recently that everything I see now.. I basically have to classify it as to be immediately discarded or worth my time to even begin reading, and even if I do continue reading then I still have to be constantly evaluating if a person bothered to struggle with (write) it or not.

Quite frankly this is.. fucking terrible? Even worse, the end of something for humanity..?

There has been plenty of crap released in the past, and even in the AI age we should be able to look at the same signals to filter through it today.
I see a perfectly good, non-AI submission. Open the comments, and the top comment is about AI.

Can we not do this? I understand your sentiment, but ... can we not do this?

IMO if i can learn from/enjoy the content then it makes no difference who/what wrote it. I'll even pay for it if I feel the content is equal in value to the price.

Reading through the first chapter, I got the feeling that it is more human than a lot of the books you might find on O'Reilly or wherever. I totally support the use of AI to help with organizing material in better ways or creating different modalities for representation. I really hate when the book is very clearly just copy pasting the output of the LLM.

Also, saw your comment response, I do feel this very same guarding and unfortunately my instinct is to assume the content is AI, which is a disservice to all the people who are putting their hard effort into putting out quality things.

I've asked myself this question as well.

Where I've landed -- once I get away from the distaste for load-bearing or a comment mentioning "spine" -- is that if the idea pushes me forward, challenges me towards improving, or otherwise informs, I'm okay with AI assisted writing.

I'm not okay with formulaic garbled nonsense, that annoys me!

There was not a single real tangable way of determining this before AI Slop.

For sure it was less to review, less options but still.

So what did you use? I used things like Reviews, skimming through, getting a referal through a blog or hn and buying from reputational sources.

HN is a filter. Same as all the other things we have.

Let's say the book was written by AI. Can you you explain what makes you less excited about this stuff?

Like is there a concrete issue with the book you have?

This is what we are supposed to have book and movie reviewers for. Just to check for slop regardless if the slop is AI or human.

But who reviews the reviewers?

What is the problem if it is AI written? Properly guided AI writes better than most human expositors.
