"It's such a strange thing," Zhang Yuan mused, shaking his head in private. "Maybe everyone's lifespan is too high, and subconsciously they don't want to be tied together for hundreds of years... Boys and girls these days are really weird. Has the pleasure level of the Love Chip been weakened? Impossible..."
Being a biologist now, he was particularly focused on the development of Extra Perception to assist the brain, and had even studied the so-called Love Chip. The Love Chip was already the pinnacle of joy humans were able to normally experience. If the threshold were set any higher, it would disrupt the brain's own mechanisms.
The ideological changes brought about by increased longevity were indeed too complex. If, in the future, technology enabling a 1000-year lifespan was developed, humans couldn't all adopt it at once. Maybe a thousand-year lifespan would become Human's Black Technology, causing the entire social structure to collapse.
