Large, awkward, expensive and hard to produce? Not the least bit scared of giant stompy robots being used in war. They're a stupid idea with a horribly limited combat role because while they offer the firepower of vehicles, they lack the armour and protection level of them, while still lacking the mobility, flexibility, and stealth of dismounted infantry.
If being oppressed by something, I might call something that looked like that 'sir' to its face, but it is going down in very short order afterwards.
Want something to be scared of? Be scared of the thousands of small networked bots armed with a small, compact 9mm pistol who are barely larger than the weapon they're carrying, and can hide nearly anywhere.
