Voyager 1 is 35 years old. Imagine if we launched a proper robotic probe with a proper engine on it. We would be able to find out which of these "earthlike" planets in our own interstellar neighborhood are truly suitable for colonization.
I'd sign up to found New America - no commies allowed.
With a properly outfitted ship it might be kind of cool to spend your life flying out as far as you can get. I wouldn't count on finding a habitable planet though. Not based on today's data. Might not be too long before our intel is better though.
