There are some obvious errors here. Larry Page is an INTJ (and is very typical of his type); Sergey is an INTP. Steve Wozniak is also probably an INTP - his book makes it pretty clear he's an introvert, and if you go by the Jungian functional stack, he's much more typical of Ti-dominants than Ne-dominants. Steve Jobs is debatable, but I would type him as an ENFP, and a psychotherapist friend of mine who's getting a Ph.D in Jungian analysis agrees with me.
