Audiences watching Pinto make his gentle kick, aided as he was by helpers and an elaborate rig, could be forgiven for not seeing much danger in the thrilling achievement. Yet like most powerful scientific breakthroughs, neurotechnologies that allow brains to control machines—or machines to read or control brains—inevitably bring with them the threat of weaponization and misuse, a threat that existing UN conventions designed to limit biological and chemical weapons do not yet cover and which ethical discussions of these new technologies tend to give short shrift. (It may seem like science fiction, but according to a September 2015 article in Foreign Policy, “The same brain-scanning machines meant to diagnose Alzheimer’s disease or autism could potentially read someone’s private thoughts. Computer systems attached to brain tissue that allow paralyzed patients to control robotic appendages with thought alone could also...
