Colonizing space & traveling between the stars is a distinction that needs to be made.
In the near future, tech advancements will open up our entire solar system to us. We will set up bases on the Moon, Mars, explore Titan & co. Those
same tech advancements will allow us to build large rotating space habitats. A ring only 400 meters in diameter that is rotating at 2 rpm will
simulate 1g. If the US military budget were diverted to these tasks for a few years, then it would be a reality very quickly.
Life support systems, hydroponics etc are simply technological limitations. They haven't been faced yet because there is no real need to tackle it at
Traveling between the stars is where the hurdles start stacking up in front of us. If we could ramp up our production of anti-matter by a massive
degree, then ships powered by it could hit 3/4's the speed of light. A ship with next gen technological advancements could easily reach the few
nearest star systems in a decent timeframe.
The real 'will they, won't they' will depend on how far away the nearest Earth like planet will reside. If FTL proves impossible, then the most likely
outcome will be a 'Passengers' type scenario. People being placed into stasis pods for decades until they arrive at their new home planet. A
lightweight graphene hull will protect against radiation & impacts. People are immobile, so life support, on board resources & stores can be kept to a
minimum. While the passengers get housed in a rotating habitat.
When you start scaling back to nuclear, fusion etc, then the task becomes much more daunting. Not too many people will fall over themselves to be kept
in stasis for centuries while they transition to a new home etc, etc.
