i wouldnt really bother listening to an 11 year old, no matter how smart he is. Does he study the mind and learning? No, he is studying to be an astrophysicist, so he should stick to his field of interest. The reason I am not bothering to listen is because I hold a Ph.D. in instructional systems with a minor in education psychology from Penn State University and am an assistant professor. I can tell you that video games are very very beneficial for the mind for many reasons and are being used by many to teach. This kid is immature and has no idea what he is talking about. I guess all of the soldiers that I have trained at the department of defense during my time as a consultant wasted their time because because I had them playing war games.
video games are a waste of time if you are playing games 24/7 and doing nothing else with you life while avoiding people, school, work, etc. Otherwise, if you enjoy them, they are good for enhancing cognition and relaxing you.
