From fright to right. As with genetic engineering and robots taking jobs away from humans, we will be horrified at first. Shortly thereafter, as we watch others use brain stimulators to speed up their thinking to make them work harder and faster, we will insist it is our right to have one. Our children will be deprived if they don't have them. Societies in which some have them and others don't will be considered unfair and elitist. Could under-performing students be forced to use them so that no child is left behind? Entirely possible.
From geek to chic. And we will be asking what colors they come in. The prize will go to whoever can turn a brain helmet into a fashion statement. Imagine Apple in the techno-clotheswear business. If anyone can do it, Apple can turn geek into chic - turning clothes wear into clothesware. We will be asking questions like, "Do you think this transcranial direct current stimulator makes me look fat? Does it go with this suit?"
There is a new divide coming, between the augmented and the non-augmented. Which will you be? Your children be? Your students be?

DIY Kit Overclocks Your Brain With Direct Current
Transcranial direct current stimulation works, and you can try it at home.
CHRISTOPHER MIMS 03/08/2012
It turns out that one of the ways you can speed up a microprocessor -- shoving more current into it -- also works on the human brain. The technique is called transcranial direct current stimulation, and while bioethicists are debating whether or not it's ethical to use it to enhance learning in children, hobbyists have figured out how to try it out at home. Think of it as the new Adderall -- without, apparently, the side effects.
Now, the first thing I have to say in this post about how to overclock your brain with a straightforward 20-minute application of electrical current is DO NOT TRY THIS AT HOME. The long-term effects of TDCS are unknown, and if you mess up and put orders of magnitude more current through your brain than is typically used in TDCS, obviously, you could kill yourself.
Now that we have that out of the way, here's how to try it at home.
GoFlow is a startup planning to offer TDCS kits for as little as $99.
Today if you want to buy a tDCS machine it's nearly impossible to find one for less than $600, and you are typically required to have a prescription to order one. We wanted a simpler cheaper option. So we made one.
GoFlow claims that their product can help speed up learning -- an effect that's already been demonstrated by the Air Force and in the lab.
Air Force researchers were delighted recently to learn that they could cut [the time required to train drone pilots] in half by delivering a mild electrical current (two milliamperes of direct current for 30 minutes) to pilot's brains during training sessions on video simulators. There is also evidence that TDCS can induce the state of creative nirvana known as "flow."
When done correctly by a licensed physician, TDCS is safe enough that it's already being used clinically to treat chronic pain. The GoFlow, on the other hand, appears to have been built by undergraduates. Given the (lack of) production values in their promotional video, I'm not all that reassured by the included testimonial from a neuroscience graduate student.
If you can't wait for the GoFlow kids to get their act together, the Journal of Visual Experiments has an elaborate video tutorial demonstrating the finer points of TDCS administration.
