The background: The "Canada 150 Research Chairs Program" is spending $117 million on seven-year grants of either $350,000 a year or $1 million a year. It's part of a campaign by numerous countries to attract scholars unhappy with Brexit, the election of Donald Trump, and other political trends, sweetened with unusually generous research conditions.

• Chun, who grew up in Canada and has lived in the U.S. since 1992, said she will launch a new "digital democracies group" at Simon Fraser University in British Columbia, which will take on the problem of the online echo chamber.
• She spoke of wanting to live in a country "with a strong commitment to public education, funding research and universal health care." "That makes a real difference to society," she said. She added, "Some of my friends work in climate research. Funding for that is disappearing and that’s disturbing."

Aspuru-Guzik tells a similar story. He will become a professor of computer science at the University of Toronto. He will have a concurrent position at the Vector Institute, an artificial intelligence research center where Geoffrey Hinton, the father of machine learning, is chief scientific adviser.

• After 20 years in the U.S., Aspuru-Guzik worried watching the rise of the Christian Right and then the Tea Party. When Trump won election in 2016, that was the final straw.
• Harvard came back with a "generous" counter-offer, it wasn't enough.
• "They couldn't change the president. And they couldn't change the zeitgeist," Aspuru-Guzik said. "So I left."

The bottom line: "Canada is not perfect — “not a utopia,” Aspuru-Guzik said. “But I place my bets on Canada rather than the U.S. as a place for my kids to grow up.”
