Imagine a space ship, hurtling through space, to some destination unknown to passengers. The systems that maintain the ship were all masterfully designed eons ago and the generations of passengers have no idea how they work, but the creators made sure to make them to be self maintaining in perpetuity. The passengers don’t even think about the systems or even have awareness of them, the knowledge of their construction has long been lost. This is the future of technology, the space ship is Earth.
