I think all ends of the human spectrum are important, and that we shouldn't even be thinking that people aspire to be the same as each other. I strongly believe that rather than working towards one model of an 'optimum individual' we should work towards a model of an optimum community, or optimum team, where everyone expresses their individuality. Coincidentally merrymaia has posted a quote that makes the same point:
Kirk: Spock, these cadets of yours - how good are they? How will they respond under real pressure?"
Spock: As with all living things, each according to his gifts.
