We will make space probes that don't require fuel, but will operate with solar wind. We might even be able to travel to the outer limits of our solar system with nuclear-powered rockets. We're bound to find more planetary systems in the next 100 years. One of these planets might have primitive life on it, and maybe even intelligent life. They might even look like us.
Interplanetary travel allows the human mind to go further.

I see more children growing up with parents than without parents.
