Why are so many users in the comments on here fear mongering? Don't you understand we already have dumb solutions for killing and making war? Bombs, bullets, Chemical and biological weapons, non of which need a complex robotic platform. How will human shaped robots change anything when we can build flying, hovering grenades and mass deploy them with COTS components?
You know what does need a complex platform like Atlas? Disaster Rescue, Medicine, Telepresence, Automation etc
