The universe is infinite and therefore has enough room to handle a Jupiter-sized brain for everyone if so desired. Once we figure out how the human brain works, see http://www-hbp.scripps.edu/home.html and how to achieve full mental satisfaction, we will better understand what effect such full mental satisfaction will have on current paradigms such as material desire, and therefore know which technologies to give priority toward in order to satisfy the same. Of course if we find the ability to reach a place beyond Utopia (Entopia), where humans exist in a state of pure energy, then all these material world issues become academic.
