If we get access to infinite energy and resources, then the answer to all your questions is YES. But space.time is not infinite, far from it. We can easily imagine, eg. computational problems (ie. computer programs that can easily be written) that would require more memory than the number of particule in the universe would allow, or more time than the life expectancy of the universe would allow. So unless we are able within this space.time left to invent a way to create new universe or survive a big crunch/big bang event, or a cold death, no, there's no infinite energy and no infinite resources to be taped, and therefore: - world hunger is not a problem of resources, but a political problem. The question is whether we're ready to gather in a concentration camp the psychopaths of the world, and exterminate them once for all. - yes, we have already more than enough food. - all hints are that cancer is a man-made illness. Once you've removed the psychopaths who build poluting processes to earn more $money or more power, we should revert to a more natural and canceless world. - nope. It is not an economical crisis, it is an economical system set up by those psychopaths to keep accumulating money and power. They already own 99% of the money and of the power, but they still need to acrrue it at a significant percentage each year. I should also mention, that assuming a population growth such as we double the population every 20 years, going to space would not solve any "overpopulation" problem if it was any more real than human-made climate change, since that would just mean that you would have to colonize new planets every 20 years. Very soon, the whole galaxy would be "overpopulated", and then soon enough the whole universe. So going to space, offers no solution to "we". However, having a space ship, and being able to leave this planet of psychopaths, crazy people, and savages, would solve "MY" problem! I would at least escape from this asylum-prison! And there's hope the galaxy is big enough that if you escape, the US government and the banksters won't be able to catch you up to make you pay taxes and interests on the debt. Healthy and educated people are looking for a way out, space mining serves only to build bigger, faster and better space ships to go farther, until we can get out of the reach of the psychopaths. And THIS would be the BEST solution, if you don't like the concentration camp/final solution.
