If humanity doesn't perish in the next hundred year and masters interplanetary spaceflight, antimatter drive is the logical next step in propulsion after fusion.

Interstellar spaceflight will become (barely) feasible once spaceships can reach velocity between 0.02 to 0.1c are possible. Even assuming non-100% conversion efficiency, antimatter has enough energy density to provide this capability.

Interstellar flight is a new physics problem, not a smash-the-tiny-rocks-together-to-make-bigger-bang problem.

We're not going anywhere without a revolution in our understanding of the universe.

		You don't need new physics for interstellar spaceflight - 16 km/s of dV is enough. you don't even need to go that much faster to slowly spread among the stars. There are a lot of smaller bodies all the way from Sun to Alpha Centauri. As long as you hop between them within reasonable time in a few thousand years you can become a true interstellar civilization, while going at much-slower-than-light velocity (similar to Polynesian colonization of Pacific).

		Not with that attitude, we're not!

Maybe. Beamed propulsion makes a hell of a lot more sense in the solar system.
