I'm not so sure. He seems a bit too enthusiastic to me; slightly artificial.
I suppose it would cause some cognitive dissonance. One question I had while thinking about the (purely hypothetical) dissonance was : "Is he being overly enthusiastic, or is my low-key behaviour a subtle result of years and years of programming and debugging in an imperative model, where I literally have to internalize the computer, the Von Neumann architecture, and did I somehow end up being an unemotional VERSION of IT, a robot-human hybrid?!". A horrific thought, eh?! :-)
Von Neumann programming would make you overly excitable, what with all these state changes and side effects.
Pure functional programming leads to immutable calm.
