How technology changes our sense of right and wrong | Juan Enriquez

What drives society’s understanding of right and wrong? In this thought-provoking talk, futurist Juan Enriquez offers a historical outlook on what humanity once deemed acceptable -- from human sacrifice and public executions to slavery and eating meat -- and makes a surprising case that exponential

Episode Summary

Executive Summary: Juan Enriquez argues that notions of right and wrong are not fixed: they evolve over time and can shift rapidly as technology changes society. He uses history, slavery, gay marriage, and synthetic meat to show that moral judgments require humility, forgiveness, and a willingness to find common ground in an increasingly polarized world.

Main Topics: Moral standards change over time: Enriquez argues that practices once seen as normal—human sacrifice, executions, slavery—were later judged immoral, showing that 'right and wrong' is historically contingent. Technology reshapes ethics and social norms: He contends that new technologies alter what societies accept, from industrial energy reducing reliance on human labor to social media changing public opinion and conflict dynamics. Polarization as modern trench warfare: He compares social media-fueled political and cultural conflict to World War I trenches, where people are forced into opposing camps with little room for nuance. Social change on gay marriage: He uses the dramatic shift in public opinion on gay marriage to illustrate how activism, visibility, and media can rapidly transform morality and law. Exponential technological acceleration: He emphasizes that technology is not just changing society, but doing so exponentially, which accelerates shifts in ethics, economics, and behavior. Humility, forgiveness, and community-building: He closes with a call for humility when judging the past and forgiveness toward others today, urging listeners to build community rather than cancel or exclude opponents. The future of food and values: Synthetic meat is presented as an example of how cheaper technology can make previously normal behaviors, like eating meat, look morally different in hindsight.

Key Arguments: Right and wrong are not static; they shift across eras as societies change. Many historical injustices persisted for centuries because they were culturally normal at the time. Industrial energy and machinery helped end systems like slavery by reducing dependence on human labor. Modern social media creates polarized 'trenches' that reduce dialogue and increase moral absolutism. Public attitudes can change quickly, as seen in the rapid reversal on gay marriage. New technologies can drive ethical change by becoming cheaper, better, and more widely accessible. People should judge the past with humility because they likely would have conformed to the norms of their era. Forgiveness is necessary to preserve dialogue and community in divided societies.

Data Points: Public opposition to gay marriage in the U.S. (1996): Two-thirds against - Used to show how quickly moral attitudes can reverse over time. Public support for gay marriage today: Two-thirds for - Illustrates the dramatic shift in social norms and ethics. Oil energy equivalence: 1 barrel of oil = work of 5 to 10 people - Supports the argument that energy technology replaced human labor and changed economics. Synthetic meat price in 2013: $380,000 - Cited as evidence of rapid technological decline in cost. Synthetic meat price today: $9 - Used to show exponential improvement that may change eating habits and ethics.

Pivotal Quotes: "What if right and wrong is something that changes over time?" — Juan Enriquez: Introduces the central thesis that morality is historically contingent. "We're shooting at each other, we're shooting at those we think are wrong with posts, with tweets, with photographs, with accusations, with comments." — Juan Enriquez: Describes social media as a modern form of trench warfare and polarization. "This is a time to build community. This is not a time to continue ripping nations apart." — Juan Enriquez: Final call for forgiveness, dialogue, and social cohesion.

Implications: Listeners are urged to resist moral absolutism, recognize how technology reshapes ethics, and approach disagreement with humility and forgiveness to rebuild common ground in polarized societies.
