What is the point of all that when we will we dead before we could see that future... Just focus on your life...
Hey, if one of the things that gets "developed" in our lifetime is immortality, a lot of us might be able to see it.
We have flying cars.
We can travel space.

I think what most people mean when they say those things is practical/easily accessible to everyone flying cars/space travel. And I don't know about you, but I would rather not have to wait several decades (at best) to reach the nearest star system. That's not space traveling, that's space crawling.
