The fact is that everywhere I look, I see exciting new technologies on the horizon, new drugs, new knowledge of bacterium, new materials, new battery technologies, ever increasing data speeds & computing powers for ever decreasing power consumption. Sure there will be disruptions along the way, but folks; The Sun will rise tomorrow!
