Meh. If someone wants to "hunt" you with a robot they can already do so with a UAV (think MQ-1 Predator, not an off-the-shelf quadrocopter). It is an already existing true and tested technology. Large governments around the world already maintain literal armies to maintain them and efficiently employ them to kill people. The fact that that weapon is not aimed at you or me is merely a political decision. With legged robots a lot more development is needed before they can do the same. I guess what I want to say: These robots are not deadly yet. The kind of people who can turn them deadly can already kill you if they want. I don't see why you should worry marginally more.
Bombs cause infinitely bigger international uproars for good reasons.
Robot assassins that cannot die change the calculus. Governments don't have to risk losing their human assets in order to take out a target. They can just send out a 4-legged drone to prick them with polonium and call it a day.
> pretty terrifying to think we are soon to have people hunting robots
for the robots, maybe
Animal traffic is a lucrative and it seems as illegal as unstoppable. My bet is that if this robots will deploy in a signifiant number, the people soon will realize that can make a life if they trap, club and dismantle expensive robots for selling metal parts and any valuable cargo that they would carry. Will be also illegal but some will try anyways. Anything electric can be insta-fried with a higher voltage or, more slowly, with a cheap molotov cocktail. Not much different than hunting a bear or deer, maybe more profitable.
