Why can't I be both? The duck in the picture is clearly both.If forced to choose, then I'd say duck. I imagine ducks have more fun than robots, plus being able to swim is fun. If there's another fuck-off flood, the ducks will survive. Robots, not as likely.
I would have to say ducks because they can swim, fly, and walk. Robots can only ponder their existence as man made machines. Once Zombie Hitler comes back in the year 2012, the robots will be our only defense. The ducks however lack the mental capacity to give a shit about anything other than eating and having sex, much like the Smurfs.
I just want to make things clear by saying that I also "lack the mental capacity to give a shit about anything other than eating and having sex." I'm clearly on the pro-duck side. Now I'm off to eat a taco and hump a tree.
