I think the author is better off self publishing, based on my personal experience:

I wrote ten tech books for big publishers (McGraw-Hill, J. Wiley, Springer Verlag, etc.) and I was so happy being a published author. However, about twenty hears ago I moved to self-publishing, finally ending up using Leanpub. I am much happier only writing self-published eBooks now because I can update my old books as needed. I still write new books from scratch (just started a book that is basically a rant against over-spend of SOTA LLMs called ‘Winning Big with Small AI’) but hardly a week goes by without an update to an older book.

Writing is great, and even better when not attatched to a conventional publisher.

Austin: if you are here, good luck, and enjoy writing!
