I hate to be cynical, but I noticed that the author is an adjunct professor. Is he all that firmly rooted in academia? Should we take his opinions all that seriously?
I like to read what OTHER highly/profoundly gifted people say about HG/PG students. Their opinions matter most to me, because they've been there. I especially don't agree with the statement that parents are poor judges of their children's capabilities. It must have been fun to be born in eras when parents WERE respected as the foremost authorities in their children's lives, because we happen to LOVE them the most!
