The point is that "you can invert the rewards signal on a Tesla and turn it into a people mower" isn't exactly a dunk on the point above them. We're not worried about Tesla having (someday accurate) people detection because we're not worried about them using it to kill people more efficiently. Indeed, generally people want Tesla to get very good at that!

So automated tracking is bad when attached to a gun because it more easily enables the rest of the concerns laid out in the thread. It's not some hobbyist "paintball the squirells in my yard", but a government-purchased, corporation built project with an explicit, obvious goal in mind. Disregarding that because many other things _could_ be used for bad with a couple lines of code is not the right call, imo.
