I'm 25, but I think some are blatantly obvious: > Food distribution The world produces enough food to feed everyone, but there isn't a framework in place to eliminate waste and feed starving people at the same time. > Education Lots of people are working on this already, but highly effective education tailored to every specific person available for free, worldwide, would be a game changer. > Infrastructure The US in particular is falling way, way behind where it needs to be. Look up the situation with bridges, and that's to say nothing of our electrical grid. > 100% Renewable energy No brainer but difficult to solve. > A new way of interfacing with computers Mouse and keyboard are great, but what if we didn't have to use analog methods for communicating intent to a computer quickly and unambiguously? Could also allow for paralyzed/incapacitated people to communicate easily and maintain social interaction
