Im on the spectrum, and I had the same impression.

I read the entire series in like 2 weeks. I dont think I've ever related to a character more. I am an introvert and am on the spectrum, and I have always thought of these things as personality defects. I feel like I've spent my entire life learning how to be human. But seeing how likeable Murderbot/Sec unit was, even with an introverted and awkward personality, made me look at myself in a new light. I'm not defective, I'm just different, that's all. I've become much more accepting of my own personality since reading this series. And being accepting of myself has helped improve my relationships with others. Its funny how books change your perspective. I read the first book expecting an exciting scifi adventure, and ended up getting a epiphany about myself.
