Prospects and Dangers of Transcranial Direct Current Stimulation

So there's evidence that electrical stimulation to the brain can increase memory retention and even enhance creativity; and running electrical currents through your head can potentially be unhealthy for your brain..

The current state of this technology reminds me of what acupuncture can do—it mostly stimulates the nerves and muscles and encourages blood-flow to the pin-prick.

But is this just the beginning? I think a futurist would say so. Acupuncture is ancient, but brain science is in its infancy and is backed by the internet and logarithmically-improving computational instruments.

I'm glad this article makes a reference to the history of shock-therapy and the science-fiction it inspired, because the potentials that this EEG tech is bringing to light area mind-blowing. Then again, all the life-extension and deep-learning AI technology that billionaires are steering towards sound crazy too.

I'm guessing these EEG kits will be the next major thing in wearables, maybe in 4-5 years some iteration will be adopted by the early majority. The machines can already give feedback if there is heightened brain activity or calm brain activity. How is that any different that the step counter and heart-rate monitor on your fidbit?
