Big Question about bringing SciFi to the real world!

Fifty years ago, Eletro Shock Therapy was used, without know how and why it alleviates depression…Today, we know about electrical activity at neural level (circle back to chapter two on neurons)…this knowledge now is used and the question that has been asked  is “Can we jolt our brains so that we become smarter”

Some one decided to test this, so at MIT, in a Psychology Lab, Professor XXX is doing an experiment where subjects put on a hat that gives them a very mild electric shock.  As it turned out, these subjects become more efficient and more accurate, in solving math and verbal puzzles; in other words they became smarter as a result of more neural activities–>release of neurotransmitters–>faster problem solving….

So, what is your BIG QUESTION about something that you learned in this course, that has yet to be developed, used, implemented in the future…stimulating the brain for the purpose of becoming smarter was a sci fi, fifty years ago…now, it is being tested with promising results…what is something that you think is far fetched that could become a reality 50 years from now?  Be creative, be imaginative, and let your thoughts and knowledge take you to the next level of curiosity!
