Video said this prototype was $16,000. Yet prototypes are always vastly more expensive than mass produced. I bet they could get the cost down to 1000 bucks or less.
I can see some real benefits for whomever uses them. They don’t get tired, get insect bites, have to eat, become Sick, get sad or afraid. I see them being used in ambush situations where they could sit immobile for days waiting for a supply column etc as you said. The only negative is their recharging needs, which is why I think they would be ideal for ambushing.
Personally I detest their development and use. You know it’s just a matter of time before some Bill Gates type nerdy dictator gets an army of these.
nylon plastic mesh netting with studded with metalic barb fasteners conneted to a high voltage charged capacitor could be used and sprung to trip them up and short them out if they are on attack mode. Bolas like South American cowboys used could trip up and take these down. I wonder if a tazer could do it...the voltage surge could emp them.
