One fallacy and criticism about future studies and futurology in science, in general , is that all time spent looking into and predicting the future is beneficial ,(and no pun intended), worth the time.
An area that might even to me fall into that category would be deep space studies. Even with my appetite for the mysteries of time and space and what might be out there I see time wasted on studying of things and locations the have no effect on our immediate need to move to protect the human race's survival. I believe if you crunch the studies available from many hundreds of sources of data we have maybe less than two generations until the time when we will be living on earth in a spacesuits and artificial environments. From that point in time to complete exhaustion of all resources natural or artificially or chemically produced or manufactured is massively unpredictable. Even if we plug in the probabilities of massive reductions in worldwide population from many predicted and in my opinion certain events.
The time and resources spent on Deep space studies with regards to even deep space telescopic exploration , in my opinion should be spent exclusively on near space study and exploration totally and completely for the purposes of colonization ,human survival, or even more realistic in the near term robotic harvesting of resources from other bodies in space to assist in Human's Earthly survival . I have yet to see evidence that the technology is even remotely close, let alone proven , now or even in the next 4 generations that we will make us ready for any practical or large scale Human travel into deep space.. especially when you look at resource and economic hurdles. Any thoughts, comments, inputs would be appreciated.
