The funding has long been moving away from space exploration and more towards information technology, robotics, and medical/biological research. The picture in my mind of interstellar travel in a century looks much more like sending an unmanned craft at high acceleration with frozen, fertilized embryos and robotic caretakers, than attempting to shuffle soft pudgy mammals across the galaxy.
well, a little bit more of "technology, robotics, and medical/biological research" and may be these mammals can be made a little less soft and pudgy :) . Especially considering that any promising high specific impulse propulsion systems are expected to have low trust (thus low acceleration for long period of time)
