I finished this out of spite because I wanted to DNF but was already 60% through. So overwrought and boring and dragged down by endless filler anecdotes and tangents from the author. I also really disliked the overall tone of the writing which seemed to paint problems that have plagued autism research as positive. The author also seemed to uplift stories from lower support needs autistics as inspiration porn while hand-waving away the cases of higher support needs autistics, which gave the book a voyeuristic, clinical tone that was hard to appreciate (I had similar issues to The Body Keeps the Score). 

Comes across as outdated and incredibly boring for little to no knowledge gained. This would be a good read if you know absolutely nothing about the history of autism, but I didn't feel like I gained enough knowledge for how long this book was.
