I used to argue this way, too. But i forget if it was NdgT or someone else said basically that there's no real reason to leave right now for interstellar travel because advancements in technology will make future travel take less time - the future travelers may pass the present travelers.

So what, we wait until we have wormhole technology?

I say we start now. maybe tech improves, maybe we get wormholes. If so, maybe we can go "cut 'em off at the pass" and move the present travelers to the future ship(s).
