How is it that we're on a technology forum and people continually insist that we've achieved the maximum rate of advancement? Also we most certainly do not spend all of our resources advancing areas of technology that would sustain more people, for instance I think there could easily be more research put into food growth/production/sustainability and perhaps things like housing development than are currently being done, but since there is no impending doom from overpopulation we tend to spread our interests around as the free-ish market allows. Everything we produce isn't going to make it easier for more people to survive, but I'm sure much could be done if it became a priority.
