The vast majority of humanity will never experience spaceflight. So it's going to be a vicarious experience for most of humanity regardless.

If we send up thousands of probes we might find that there are livable conditions for humans under the ice of some of the icy moons or in the clouds above Venus. Then we can start sending people to those places where they have a chance of survival.
