I think there are some very good reasons to believe your opponant WAS a human:

1) Opening choice led to a locked position with good knight versus bad bishop,
typical anti-computer moves (avoid tactical, open positions).
2) Move 35.e5 is not computer like, giving up a pawn in order to make black's
bishop bad and to gain access to the center for his white's king.
3) The amount of time used when surprised or when making a tough decision, such
as for move 32 after the somewhat surprising 31--a4.  Also spent a lot of time
on moves 35.  More time than a computer playing blitz would probably take for
those moves, since I doubt that there would be a fail low in those particular
positions.
4) Perhaps most telling, repeating the position at move 46-47 when in a
completely won position, something humans do often, to gain a bit of time to
think, while a computer usually will repeat positions only when happy with a
draw.

You mention the flawless play from moves 46-78, but by then he was totally won
and just ran around grabing material for insurance.  Everyone knows comps like
to grab material, but humans will also grab material when there is no risk, and
from 46-78 there was no risk.  Black was totally tied down.  In fact about the
ONLY thing that seems computer like to me is that in a blitz game there were no
blunders.  But a decent human will not ALWAYS blunder in blitz games, especially
if the position isn't wide open.
