Is brain boosting ethical?

While the idea of a simple, inexpensive, and effective device that can enhance your brain might sound appealing, but it's ethically questionable:

"We ask: should we use brain stimulation to enhance cognition, and what are the risks?" explains [Dr.] Roi [Cohen Kadosh, who has carried out brain stimulation studies at the Department of Experimental Psychology at Oxford]. "Our aim was to look at whether it gives rise to new ethical issues, issues that will increasingly need to be thought about in our field but also by policymakers and the public. This research cuts to core of humanity: the capacity to learn," says Professor Julian Savulescu. "The capacity to learn varies across people, across ages and with illness. This kind of technology enables people to get more out of the work they put into learning something."
