The "Writing this book" section accidentally implies that LLM's were used for 2/3rds of the manuscript.
I think they probably mean that LLM's just gave them a lot more to write about, but I think it would be a good idea to clarify.
I am not reading it like this - in fact ChatGPT was the first thing out there that would be able to assist them in writing, and less than a third of this book was written after release of ChatGPT. To me it just looks like marking important events in ML/AI field on the graph.
