science

Nobody can be excited for anything. Whether or not it's possible in even the next century or two, I still think it's awesome that there are dreamers out there trying to make at least a solid theoretical plan on how to accomplish stuff like this. I also think people are discounting the exponential rate of knowledge we accumulate every generation. It might be awhile, but unless society collapses, I wouldn't be surprised if we have interstellar propulsion like this in the next couple centuries. Hell, I expect to see a thriving commercial space industry in the next 50-some-odd years within our solar system.
