I believe the biggest opportunity for human progress is the development of some kind of affordable, portable & clean energy system. From 'energy' you can get most everything else you need. People could pull water form the air in dry regions. Grow food indoors where the environment is not supportive. Power computers and mobiles for education and information distribution. Run bug zappers in malaria prone regions. It really does seem the foundation to further progress for much of the developed world. I believe once we have this we will see progress on the scale of the industrial revolution.
