According to wiki [1]: > At a constant acceleration of 1 g, a rocket could travel the diameter of our galaxy in about 12 years ship time, and about 113,000 years planetary time. If the last half of the trip involves deceleration at 1 g, the trip would take about 24 years. If the trip is merely to the nearest star, with deceleration the last half of the way, it would take 3.6 years. 24 years is one generation of humans. And 113,000 years is still less than 600 million years. Speed of light is not a problem. Making that ship self-sustainable and even being able to accelerate to 0.999 c might be.

If we can somehow figure out how to keep astronauts in stasis some way or the other, that would remove the need to get anywhere in under 100 years or so. If humans become cyborgs and lose the need for standard forms of nutrition or air, that helps too. If methods for life extension are found, the same.
And if that fails, well there's always robots. Or potentially colony ships. Nothing says the automated ship has to be 'on' for the duration of the journey, only the launch and destination.
with any of these ideas, the speed of light becomes even less of an issue.
