Emotions
I may be taking this a bit too seriously, but I was wondering, if something like D.A.R.Y.L. was actually created, how would it/he/she experience emotions? For example, I can imagine that the emotions experienced are simply programed in to the computer in question, and are then activated when a required situation is around the computer, like if you press a key on a keyboard, that makes the given symbol appear on the screen. At least in D.A.R.Y.L.'s world, my theory is supported by this quote:
Turtle (at the lab): So, how does it feel?
Daryl: Just the same.
This leads me to believe that, while he had "amnesia" he assumed that everyone else was the same as he was (meaning they analysed everything, etc.), then when he was repaired he regained the knowlege that everyone else is different.
Any ideas on this?
