Uber just notified workers it is naming Zoubin Ghahramani as chief scientist, a new role overseeing the company's artificial intelligence and machine learning efforts.

His appointment follows last week's departure of AI labs head Gary Marcus, a move first reported by Axios. Ghahramani, like Marcus, joined Uber as part of December acquisition of machine learning company Geometric Intelligence.

Until now, Ghahramani had been based in Cambridge but will move to Uber's San Francisco HQ to take up the new post.

Why it matters: Uber needs to retain key talent, especially in its most future-leaning endeavors like driverless cars and machine learning, both areas that have seen recent defections.

Climate change goes mainstream in presidential debate

The most notable part of Thursday’s presidential debate on climate change was the fact it was included as a topic and assumed as a fact.

The big picture: This is the first time in U.S. presidential history that climate change was a featured issue at a debate. It signals how the problem has become part of the fabric of our society. More extreme weather, like the wildfires ravaging Colorado, is pushing the topic to the front-burner.

Finally, a real debate

A more disciplined President Trump held back from the rowdy interruptions at tonight's debate in Nashville, while making some assertions so outlandish that Joe Biden chuckled and even closed his eyes.

  • A Trump campaign adviser told Axios: "He finally listened." 

The result: A real debate.

Biden to Trump: "I have not taken a penny from any foreign source ever in my life"

Former VP Joe Biden pushed back Thursday against allegations from President Trump, saying he had never profited from foreign sources. "Nothing was unethical," Biden told debate moderator Kristen Welker about his son Hunter's work in Ukraine while he was vice president.

Why it matters: Earlier on Thursday, Hunter Biden's former business partner, Tony Bobulinski, released a statement saying Joe Biden's claims that he never discussed overseas business dealings with his son were "false."
