IMO we are probably on the brink of the last possible society that can on a technical level. I would say, nukes, and even drone bombs etc… are unlikely to be utilized, simply due to collateral damage, infrastructure damage etc…
However, things like the boston dynamics spot etc… We’re probably a decade away from when 1 person can control an army of perfectly loyal soldiers.
It’s true… but with all things it’s a matter of quantity of people you need to be loyal… IE one commander who agrees with the cause, vs 100 soldiers that could talk about it.
Plus, it’s far easier to grow a concience on the field looking in the eyes of the children you are murdering, vs sitting in a computer or robot lab having no “need to know” what these robots do when they leave your office
