Do you think Humans will colonise The Moon and Mars someday?

I would be surprised. In terms of space exploration, our technology has advanced very slowly considering how many years ago we landed on the moon.

Who cares about space when my nuclear button is bigger and grander than yours

Yes. Competition will provide an incentive although it may take several more decades to reach Mars. The US is lagging behind, but China, Russia, Japan and India are planning Moon bases in the coming years. Japan is currently looking at a potential site in a 31 mile long cave recently discovered on the Moon. India's second unmanned Moon landing will be this year. Current plans set the target date at 2030 for manned landings by China, Russia and Japan. China's Moon base target is around 2036. These are all stepping stones to Mars.

Not in our lifetime--Scientists still haven't figured out how to prevent the radiation/cancer problem as well as the vision problems affecting astronauts for long space flights

Why on earth would we spend trillions to live on the moon?  Astronauts yes.  Colonies?  lols no.  Mars too, they'll maybe get a population up to a few hundred by 2100, many of whom will be born on the planet to scientists, raised to be future scientists.

Maybe, but I doubt it. We're having a difficult enough time coping with life on our own home planet. I see no incentive for colonizing the moon. Mars is even more of a stretch, and the atmosphere is probably too wrong for us. My guess regarding space exploration is that it's going to be very different from the glory days of when humans were discovering "new worlds" (as in new continents) to "conquer" right here on earth.

Also, I just can't see any reason why we should want to set up colonies (call them what you will) on the moon, Mars or any other planet or satellite. Life is far from ideal on earth now. There's so much misery, disease. So much is wrong for so many people with just trying to stay alive and make ends meet in the here and now.

I'm not saying all this to be pessimistic; nor am I a negative person by nature. More like "first things first", There's so much poverty on our planet, so many people in need, too many,--my two cents perspective on things--that needs doing to make life satisfying for people in our time. It may some day be possible, even desirable for humans to (whether literally or figuratively) conquer new worlds, settle elsewhere than earth but we and our lot in life as a species strikes me as too problematical,--we're too imperfect--to even consider such a possibility today, in the 21st century.

A thousand years from now, who knows? I can't see colonizing other planets being seriously on the table any time soon.
