Technology may soon be able to dial cognitive states on demand. Andrew Huberman: "The real holy grail in all this is the ability to dial in cognitive states." "I can imagine putting on a pair of glasses to sit down and do some work… and for the next 40 minutes you'll experience the kind of focus that you only had a few times when you had all conditions right." "The amount of things you can do to modify brain state through this region, just the eyes, ears, and superficial nerves that run around there is just phenomenal." "If I were to personally invest in any companies doing that sort of thing, that's the body area and the sorts of things I'd be really focused on." @hubermanlab @daisydwolf(a16z)
