Neuroscientists' Open Letter To DIY Brain Hackers
RadioLab's 9-Volt Nirvana episode discussed how DARPA uses tCDS to enhance sharp-shooting ability.At the end of the episode, the reporter conveyed a sense of loss when the tCDS system was no longer available to her. She sounded like a drug addict that pines for that feeling of their first high and then risks spending their life in vain trying to recover that feeling.If your life literally depends on a skill and supervised tCDS can improve it, then the reward may outweigh the unknown risks. But for other tasks/skills, it is difficult to justify.Edit: typos, clarityhttp://www.radiolab.org/story/9-volt-nirvana
