Yuval Noah Harari in The Atlantic:
There is nothing inevitable about democracy. For all the success that democracies have had over the past century or more, they are blips in history. Monarchies, oligarchies, and other forms of authoritarian rule have been far more common modes of human governance.
The emergence of liberal democracies is associated with ideals of liberty and equality that may seem self-evident and irreversible. But these ideals are far more fragile than we believe. Their success in the 20th century depended on unique technological conditions that may prove ephemeral.
In the second decade of the 21st century, liberalism has begun to lose credibility. Questions about the ability of liberal democracy to provide for the middle class have grown louder; politics have grown more tribal; and in more and more countries, leaders are showing a penchant for demagoguery and autocracy. The causes of this political shift are complex, but they appear to be intertwined with current technological developments. The technology that favored democracy is changing, and as artificial intelligence develops, it might change further.
