"The remedies are easy to prescribe. We must improve civic education in schools, raise awareness about cognitive biases throughout society, spend more time with people from other political tribes, reduce and regulate the use of social media, rework the political structure to foster more political parties and equal representation, double down on free speech, feverishly guard election integrity, and support a new Republican champion other than Donald Trump. Yet in practice these goals have been impossible to achieve. Two broad and overlapping global trends will only make reversing the free-fall harder as the 21st century marches on. First, technology is getting more sophisticated—at a dizzying pace. The positives are huge. The internet democratizes education. Streaming innovations like Netflix enrich entertainment. New products like self-driving cars revolutionize transportation. Highly sophisticated research dramatically improves medicine. Pioneering technologies substantially broaden the distribution of necessities like food and clothing."
