My honest opinion is we are pretty much at the end of our 'tech tree' and there is little else in the way of big advances that will allow us to travel beyond the stars. The only future tech that is theoretically possible at this point is fusion energy, which would be great, but would still not allow for reasonable space travel for any biologic.
Theory of relatively very cleanly disallows movement of mass at near light speed, so its extremely unlikely we will ever leave our solar system. There is no other known phenomenon that we could speculate that would make things any easier.

This reads to me like physics as presented by Francis Fukuyama. I don't think I've ever seen a scientist seriously propose this view.
