Kriston and acs,
I like your take on early college. There a plenty of other options available (dual enrollment, working in a lab, mentorships, self-study...) that don't lock a kid into a career so early. Self-study and working with those in fields of interest helped me to settle on a field without worrying about switching majors. However, college earlier (maybe 14 or 15) may work for some kids who already know what they want to do, especially as graduate or medical school after college adds several extra years to one's education... Options are a good thing!
