I too found this significant. I personally very much relate to the feeling of "a vast open space where all my knowledge runs free with my hyper-connected brain".
I feel like I make many more relational associations and distinctions than most people around me, and as newly self-diagnosed, relating that to my autism via the hyper-connected brain theory is very attractive.
But then I got a bit confused by the various neuroscience results I got when I googled "hyperconnected brain" -- mentions of rumination in depression, ways the brain works around physical injury, etc. I can see a common thread at some level, but it doesn't quite correlate with the simple identification hyperconnected = good = me that is emotionally so appealing.
I also strongly relate to the idea of "no borders", on more than one level. I have had similar difficulties with boundaries in social situations, and I think part of it is that I have very fluid identification. I could never understand all the people who are so worried about their identity, which to me suggests something non-fluid (I am the being i will have been, whatever that turns out to be). I can be overly trusting, and I can overshare. Conflict freaks me out, though as an adult I have learned to deal with it to an extent. And on a whole other level, since age 14 I have believed that "relations are prior to things".
And I would echo what several people said above about not seeing people as belonging to categories. That to me is elemental -- people are people; beyond that, what's relevant is what they say and do.
