Alibaba Group chairman Jack Ma told the World Artificial Intelligence Conference in Shanghai Thursday that artificial intelligence should enable people to work 4 hours a day, 3 days a week, Bloomberg reports.

Why it matters: It's a remarkable demonstration of Ma's faith in AI, given he's endorsed the Chinese tech sector's standard "996" schedule, which consists of a 72-hour workweek: 9am to 9pm, 6 days a week.

The big picture: Ma appeared onstage at the event with Tesla CEO Elon Musk, with whom he had a disagreement on whether humans can be outsmarted by computers.

Making sense of Biden's big emissions promise

President Biden's new U.S. emissions-cutting target is a sign of White House ambition and a number that distills the tough political and policy maneuvers needed to realize those aims.

Driving the news: This morning the White House unveiled a nonbinding goal under the Paris Agreement that calls for cutting U.S. greenhouse gas emissions by 50%-52% by 2030 relative to 2005 levels.

The Biden administration is moving to address global warming by setting a new, economy-wide greenhouse gas emissions reduction target of 50% to 52% below 2005 levels by 2030.

Why it matters: The new, non-binding target is about twice as ambitious as the previous U.S. target of a 26% to 28% cut by 2025, which was set during the Obama administration. White House officials described the goal as ambitious but achievable during a call with reporters Tuesday night.

More than a year into the coronavirus pandemic, some 3 in 10 health care professionals say they've considered leaving the profession, citing burnout and stress, a Washington Post-Kaiser Family Foundation poll out Thursday indicates.

Why it matters: Studies throughout the pandemic have indicated rising rates of depression and trauma among health care workers, group that is no longer seeing the same public displays of gratitude as during the onset of the pandemic.
