I recently had a chat touching on these subjects with a few friends just over the weekend and the general consensus is that if there is intelligent life elsewhere in the universe (at the "able to travel from star to star" space-faring stage), they likely have decided to not make contact with us given the current state that humanity is in (I'll leave it at this and not break this down further as I don't want to offend anyone).
As far as where we'll be in the future, I can see the potential for colonizing other planets, however it's going to take massive advances in 3d printing technology for basic structures to be put together for research stations and basic outposts to determine if planets have all of the basic materials (and in mass quantities) to allow for expanded colonization. The hardest part (I believe) is being able to produce more food than is consumed, allowing for sustainable life to be established at first and ensuring that colonists/those first setting foot on the planet don't begin reproducing until long-term viability has been confirmed/established - concern for this is specific to the g-forces required upon exiting/entering a planet's atmosphere.
Lastly as for leaving the solar system, the best hope for now is for NASA to confirm the EM drive via actual space tests (I haven't spotted any updates/press releases on this recently) and to push forward the research behind it to increase power outputs, etc. I can only hope that FTL solutions come sooner rather than later. The dream of experiencing another planet or solar system firsthand would simply be breath-taking.
