There doesn't seem to be any hope of me living that long. Interesting to think about in a science fiction world, but for now there are a lot of toys that I can't afford.

I don't think we will ever get there. The energy required for interstellar is too high, and global warming is a concern with anyone using too much energy. (Dyson spheres sound good, but mathematically they are tricky because they imply some form of global warming that you need to work around)
