Caveman: Solar Protocol

In 2635 AD, Chen Mo, an engineer at Asia's largest artificial incubation center, discovered an ark that had been deleted from history on the 100th floor underground. He soon realized that humans were not simply imprisoned by a conspiracy, but were pushed past the critical point of social networks by their own freedom, algorithms, and fear of others.

Otherwise, even if civilization has enough technology to resist the stars, it will not have the ability for two people to hold each other's hands.
