It has nothing ti do with his nature and everything to do with the scorpions inability to understand you.
What? No, the military industrial complex as a whole understands that academics don't like autonomous kill bots. They just don't care.
Take the MQ-1 Predator. Built by a team of engineers of all sorts of disciplines. 6,000 employees in San Diego. For most it's probably just a job. They might even agree and sympathize with the academics. Doesn't mean they're going to stop going to work. GA's CEO Neal Blue.... looks to be a pretty hard-core conservative, so maybe he doesn't understand what the academics are getting at. But with that much money you'd hope he's at least a little smart. He's going to keep making things that are price-competitive with the capabilities he can talk someone in congress or the pentagon into wanting. A PR officer from the Airforce that buys these things is going to point out that it's their major function and reason for existing. It literally IS the nature of the airforce to make decisions about who to go kill. The colonels and generals might even prefer if they could actually codify the rules of engagement into a robot rather than training a pilot.
And if it will mean more employment, more sales, better capabilities in low-connectivity theaters, and better or equivalent adherence to the rules of engagement, then these people are going to make an autonomous version of the Predator. You could sit these people down with the authors of this paper, have it fully explained, and the AutoPred would still be made, sold, bought, and used.
Besides, perfect is the enemy of good.
Why doesn't anyone note that the frog acted outside it's nature?
...huh. That'd be to distrust scorpions and not give free rides. Which makes sense.
