[ExI] is a FTL drive a dream without any physics to back it up?

I would agree about the generation ship comment ("tomorrow" being an
obvious rhetorical flourish). It's certainly possible that such a
thing could probably be done in a reasonable amount of time, say 10-20
years (less if there were some imminent global catastrophe), if there
were a global consensus to do so and a realistic destination. Not a
practical thing, but definitely within the realm of possibility.
