No. At least I am not so skeptical. :) Based on experience, I think we start with the assumption that we do share the same experience. Only occasionally, will you find that someone is mentally ill, deficient, or intoxicated, and then consider the experience may not be a shared one.

Personally, I think intelligence is in a large part granted, maybe near as much as it is earned.

We have this vacuuming robot at home, it scurries along the floor, works its way around table legs, avoids the stairs, and senses walls. When its battery is low, it finds its docking station and recharges itself. Oddly, even this very limited display of 'intelligence' has caused my wife and I to name it Willy, and to refer to it as 'him'. If we come home and find him caught under something, we'll say "Oh no, Willy what happened to you?"

To tell you the truth, as much as I know that our vacuum isn't sentient, I'd feel different taking a hammer to it, than I would our toaster.

Maybe you have granted me more than I deserve, just based on some clever text? :)
