I'd think if we're in a simulation you should act like Everything Is Real and continue on as you would normally instead of messing up the data set.

edit:

I also occurs to me that if we're being simulated by an AI

a) I don't really care about my super self that much

b) Any AI that is simulating me can, by definition read my mind so it'll know I wasn't serious anyway

c) This AI can also plant thoughts in my head.

At this point there's really no point at all considering anything else because either nothing matters and I have no control over anything anyway or it's reality, I do and I'd do what I do normally.
