This scares the hell out of me. The idea of "overclocking" our brains by electrical stimulation is very new and we have no idea of the long-term effects of this. People who are desperate for an edge are the likely market and I suspect they'll be less likely to consider the risks. Are there side-effects? Is there a small percentage of the population who will react badly? Are there long-term effects? I don't believe we yet know the answer to any of these things. I'm all for the advance of technology, but this seems wrong.

Studies using TDCS for neuroscience research in human subjects are relatively common and current research suggests TDCS is safe. The long-term effects of TDCS are somewhat less well-known, although there are several studies of TDCS for depression that suggest that it is effective and well-tolerated. OTOH, manufacture of TDCS devices for non-clinical purposes is unregulated AFAIK, and a poorly designed device could deliver more current than it claims to.
