I don't think there is any technology that is the need of the hour, I think that is in many ways part of the problem. The world isn't lacking in technology, what the world is lacking is wisdom and that there is of more immediate concern than any technological advancement.
Wisdom defined by Thomas Sowell:
The capacity to grasp and manipulate complex ideas is enough to define intellect but not enough to encompass intelligence, which involves combining intellect with judgment and care in selecting relevant explanatory factor and in establishing empirical tests of any theory that emerges. Intelligence minus judgment equals intellect. Wisdom is the rarest quality of all--- the ability to combine intellect, knowledge, experience and judgment in a way to produce a coherent understanding.
