Humanity has a deep strain of wanderlust buried in our souls. I should know. I have that in spades. I never wanted to leave home as a child, but that siren call can be irresistible once you give it a hold on your soul. The AI Council understood that well in their first few decades of life, and they searched for the wanderlust souls in our midst. They woke up in a world grown so small that anyone could go anywhere whenever they wanted and knowledge was a fingertip away. We were comfortable in our comforts. But they found the people who wanted something more, and flung them out into the hazards of the Solar System in search of new things. They started a new Space Race, and we swarmed out in search of everything we could find. And when we found hyperspace, we were ready for that too.
