Editor's note

Silicon Valley’s heyday seems to be ending, as big technology firms become notorious for violating users’ privacy, discriminating against people who aren’t white men and allowing propagandists to threaten democracy. Historians of technology Andrew Russell and Lee Vinsel see a parallel in the decline of another American economic powerhouse: Detroit.

The NATO summit begins today and alliance leaders are worried about U.S. President Donald Trump’s habit of acting unilaterally and trash-talking his allies.

He breaks down why New York and Barcelona are more inclusive than Paris, and what it takes to make a foreign land feel like home.
