The article touches on it, but I cannot see how would you fundamentally solve the safety issue. It will be heavy (frame and batteries) and strong (to be useful as well as move around all these batteries), comparable to a human.
Who in their right mind would have a thing that can ran out of power and crush your dog, choke a baby when it though it was a pillow or just like.. grab a knife and stab someone cause today it feels like Mechahitler.
I mean, it is essentially torture (solitary confinement for a year) but for a 30 bil sure.
My head is not the worst place to be in, I bet I could come out of it only slightly damaged.
