Please stop this, all of you. You should all be ashamed of yourselves, goading and piling on an 11-year-old. Even if you're 100% correct, none of that would be his fault—taking it out on the kid is shoddy, and also childish in its own right. The proper response is to be warm, receptive, and encouraging down the path of actual learning and creation. Get him talking about the details of the project that he finds most interesting, get him technically engaged, direct the focus away from age-achievement. Then maybe something good comes of it.
