"Flying to the moon is a myth, I highly doubt we would ever manage flying on a basic scale... We will be wiped off the face of Earth before we could manage it." - People like you before 1903 (Literally less than 120 yrs ago)

Amazing how you have knowledge about all possible technological advances even for the far future. You should write a book and enlighten us. It is not currently feasible. Just like it is not currently feasible to permanently colonize Mars. Stop speaking in absolutes for the future. Or honestly, you can go ahead and keep preaching ignorance that while the visionaries for the future actually try to keep learning and try to do something.
