I've seen him comment on it a few times over the years, though I wouldn't take my vague memories on them as canonical: He's mainly pissed off that many avid fans of some of his books and Accelerando in particular show a few patterns of thinking: 1) They miss his intent to show future for humanity that was much more of a "Warning! Do Not Enter!" than as any sort of advocacy/enthusiasm for it 2) Really pissed off that a subset of the that are ultra ultra wealthy either miss the signpost or dont care and seem to take it & other hard-takeoff singularity stories as potential maps & guidebooks on the path 3) He's annoyed (maybe not the right word) that a significant portion of people that cheer on the idea of a singularity do so in part for the hope of something like immortality, biological or uploads, specifically in a way that reinvents quite a bit of the trappings and mythos and other cultural baggage embodied in a lot of western Christianity, most notably a lot of the TESCREAL hodge podge of groups.
Again, all of this is my own dodgy recollections and paraphrases.
He's a cyborg: "the thousand petaflops of distributed processing power running the neural networks that interface with his meatbrain through the glasses." Why he is special? Who knows. Maybe he has a talent of interfacing with the nets through the crude hardware of the era. Maybe it's connections you mention.

(You can quote me on that. I hate what tech has turned into.)
