There is so much I loved about this story. And also much that rubbed me the wrong way.
What I loved is the concept of not expecting others to adapt to your way of doing things, when you are perfectly capable of adapting to theirs. I also loved the concept of taking only what you need and otherwise serving other people's needs. I loved the acknowledgement of the fact that people don't "read' people, they just guess (with the implied understanding that the guesses only work if both guesser and guessee are average NT's). I loved that the NT MC saw value in a non-NT way of doing things. And I loved that the main principle of the world Inclusion, revolved around considering others' needs so they can be included.
What I didn't like is that Inclusion, in practice, wasn't very inclusive. It was just as intolerant of other ways of doing things as NT-dominated Earth. For one, it only seemed to recognize one very narrow definition of autistic behaviour and marginalized all the others. Researchers now know that the stereotypical autistic behaviours highlighted in this story are only one kind of manifestation of ASD, and many autists are quite fond of touch or small talk, and not at all interested in lists or collections or order. This story seems to not know this and it makes Inclusion very not-inclusive to those people. Maybe I'm too idealistic, but I would have liked to see an Inclusion that actually makes an effort to be universally inclusive, not just to all autists, but to NT's too.
The other thing I didn't like is that all the NT ambassadors (and by proxy, every NT on Earth) were portrayed as completely narcissistic and totally inept at seeing things from someone else's point of view. While I have met quite a few NT's that were that way, I have also met many who show true emotional intelligence, who are quite able to adapt to non-NT ways of doing/thinking, and can easily find the value in doing so. I would like to think that people sent as ambassadors to a non-NT world would be picked from the latter group, not the former, or at the very least would be able to adapt on the fly. I just can't believe that the ambassadors were all so bad at it.
So, in summary, while I loved that this story was attempted, it just left me feeling let down. Maybe it reminds me too much of grade school, where you finally find a group of like-minded uncool kids, but are then told you're not good enough for them, either....
