I hope we see some hibernation breakthroughs in the coming years, but I think that (unfortunately) our species is going to remain “grounded” if we don’t develop Faster Than Light (FTL) travel capabilities.
I’ve been thinking that FTL might just be truly impossible which is why we don’t see ETs showing up. I know that there are theoretical designs for FTL systems, but so far the details of implementation remain elusive and the energy requirements are enormous… so, could be impossible.
Beyond that, I think humans may eventually colonize the moon, Mars, and the clouds of Venus, but I highly doubt we will make it out of the Solar System before our species dies out.
I think we should be working out how to modify/terraform the atmosphere of Venus so we can live on the surface. At the rate we're going, we're going to need that tech on Earth. So once it's perfected here, we can then get our sister planet back to functional too
Venus needs a lot of work that Mars doesn’t. I think the main problem is the rotation period. The amount of energy required to speed up the day of planet is unthinkable.

Edit: I hope to be wrong.
