Possibly. It depends on how developed they are, and maybe a few of your philosophical stances.

[Personally, Otto just isn't willing to take that risk. He thinks he'd have to sit down with one of these machines for a while before really reaching any kind of certain conclusions, and that's not a luxury he has. It doesn't necessarily bother him that so many others have been destroying the machines, though. Sapient or not, they are the ones he's seen starting all the fights.]

I wouldn't call the actuators fully sentient - or even independent - for example. But they've certainly got minds of their own.
