Yeah, but remember, that my assumption was that these machines can self improve—something that humans can’t do.
Humans are kind of fragile too. We lose our two eyes and we are blind forever. A robot can have any number of eyes and these can be replaced if they go bad. Same deal with just about any non-healing body part. And, unlike a human, a robot can be healed in hours (or sooner) vs. days or weeks.
With nanobots, you have the capability to quickly evolve new structures from very small (cell sized) machines. The capacity of extremely rapid evolution is there.
Remember, we cannot explain why we are self aware. It is quite possible that a self-improving machine could create its own sentience by accident.
Again, until these guys have some sort of regenerative power source, their primary weakness today would be uninterrupted power source.
Next to that would be the optics/vision/laser range finding.
I saw that latest battlefield robot used by the armed forces and it was basically a mounted M60 on tracks. Particularly deadly due to it’s ability to maintain fire on a target by eliminating the effects of recoil. very effective against enemy infantry.
Still, a well placed RPG round would neutralize the threat by limiting mobility either by destroying it’s tracks or optics/sensing capabilities.
I dunno, ya know someday there may be a battle hardened autonomous robot with a level of artificial intelligence that may become a stalker/killer robot, but It won’t be in my lifetime.
