Right now you have US military personnel sitting at a desk in Ohio launching missiles from a drone in Afghanistan to kill bad guys. Why wouldn't they also use killer robots when they become available?
The troubles people fear come from where the people creating and implementing law become increasingly disconnected from the enforcement, and removing people from enforcement removes a feedback from 'the ground'. A person can refuse to enforce what it perceives to be an unjust law. A union can band together and refuse to do certain things.
That can happen with robots as well, but the requirements for cooperation are lower. Fewer bad actors are required to achieve a super-bad goal. Imagine the entire police force controlled by one person. The entire army. Would that be good?
If you answer is no, or "maybe, it depends" then you also appreciate the unease that people feel about increased concentration of power that could come from automation.
If you aren't controlling them, somebody else is.
I may be mistaken but that's the first time I hear about Boston Dynamics switching to battery operated robots.
That's a big step I think!
This one seems to be aimed at domestic "helper dog" tasks.
Thus much like a roomba they will have a charging station sitting in a corner somewhere.
Is this really true? Because this sounds like a stupid reason, even in part, to make a sale.
Edit: Boston Dynamics also didn't help themselves with the "dog kicking" video. It (sort of) looks like a dog, and people were kicking it (well, not really, they were pushing it with their feet to show it good it was at balance). Obviously it's just a machine, but a lot of people saw some dudes kicking a dog.
An hybrid was made that was awesome , but I think that in the end, both companies had a different vision for what they wanted to build.
It is impressive, especially the jumps, lifts, and spins.
The trick is to aim for stylistic rather than photorealistic.
Some technology can wait till we humans can handle it.
It might be difficult to copy nuclear bombs, but this will be easy to replicate and unleash upon the world.
