My experience reading this book was somewhat tempered by my prior consumption of his past published articles on the subject, but there was plenty of new material. I would recommend it to anyone, especially those who have never read anything by him before. Other authors could possibly learn from the idea of a companion website to present audio/visual material that enriches the text.
I appreciated the "re-presentation" of his conversations with his autistic contributors, rather than simply sharing the transcripts (not worthy of a book) or barely using any quotes. One of the best actions that a neurotypical can take is the promotion of neurodiverse voices (as well as truly listening to those voices). This goes for any member of a majority when it comes to a minority.
I also really appreciated his honesty. His learning experience over time was evident, as well as how he learned from the people that he was speaking with. Not every researcher is that transparent.
