Fair warning: if you lose sleep over scary stuff you may want to skip today's post. Brian Cox, a well known British scientist, was asked to explain why we haven't found aliens yet. With 200-400 million suns in the Milky Way it is almost certain that there are life supporting planets so where are they? One theory is self replicating robots that we don't yet recognize, which is scary when you think about where we are with AI, but again no evidence of this. Then there's the Great Filter theory where intelligent life forms have to go through a number of steps before they can make themselves known but one hurdle is impossible to get past. Here's the kicker...to get to the point of space exploration you lose focus on your home planet by abusing natural resources and ecosystems making it uninhabitable. And last with all the technology comes the risk of a war with the capacity of destroying the planet. Any of this sound familiar?
