I think robots will eventually better human pioneering and adventure. When we humans get past ego and vanity then we will succeed in more efficient science and exploration. We can then replace the fun of the adventure with the fun in designing robots. Like couch potatoes; have fun and get fat. Maybe UFOs are a sort of mind game with ETs; they have fun zipping around galaxies in different dimensions or planes of existence.
