What a wonderful world that would be. Look, not so long ago the internet was an unknown thing, in fact when it was first introduced people criticized it and called it all sorts of things like, bubble, never gonna last etc. But here we are, the internet forms the biggest part of our lives right now. The world as we know it almost can't function without it. We are seeing the same thing with cryptocurrencies and what the Blockchain can do. Again, also being criticised by the masses. Here' my point:
Your dreams and visions of the future I believe are possible. The technology that we have now at some stage it was also unimaginable and perhaps too far fetched. But here we are. Will humans one day live in the moon or colonise Mars? I do think so. May not be in or lifetime nor the next generation but I do also see this as an eventuality. We are evolving as human beings, getting smarter and discovering new things everyday.
Yes, there will always be those skeptics who would rather find a 1000 ways something will not work rather than that 1 way that it will! This of course doesn't stop the human race overall and we just keep progressing and proving those skeptics wrong!
