One day a person will see a Spot robot and smile at its cuteness, then notice that there's no way to get past it, no way to have it not decide where you can and can't step towards. It won't have a gun, but that person will no longer have a reason to smile at them in the future.

Later you will have a Spot robot chasing a person and getting it to stop, surrendering at the machine without being threatened by it, but just by recognizing that there's no longer a point in running away.
