I was one of these children. In hindsight, I think it damages your development in many ways to the detriment of long-term outcomes. The unfortunate environment and instability of my childhood living situation, which ultimately derailed the "child prodigy" track, may have put me in a better position to actualize my abilities despite the obvious negatives at the time. I knew a couple other kids like me that stayed on that track, none had great outcomes.

The intense focus on academic learning does very little to prepare you for being a productive human out in the real world, which is tacitly a part of the environment normal kids grow up in. That many of these kids are dropped into the real world even earlier than their age peers due to accelerated schooling just compounds this.

One the upside, one elementary school that had no idea how to teach me sat me in front of a computer and left me to my own devices. So I taught myself to program.
