Bloomberg - Evening Briefing - Threatening to quit

What began as a curious, largely unexplained announcement on Friday afternoon transformed over the weekend into a human resources firestorm. Sam Altman’s shocking departure as chief executive of OpenAI has led to almost all of his former employees threatening to quit and follow him to Microsoft. That is, they say, unless the current board of OpenAI—the one that showed Altman the door for not being “consistently candid”—resigns. More than 700 of OpenAI’s roughly 770 employees signed a letter to the board stating they are “unable to work for or with people that lack competence, judgment and care for our mission and employees.” So what is the kerfuffle really all about? At the heart of this Silicon Valley drama is a much bigger question than Altman’s next posting: it’s whether artificial intelligence should be looked upon as a commercial opportunity or as a potentially dangerous technology. There seems to be some disagreement. —Natasha Solo-Lyons and David E. Rovella

Far-right candidate Javier Milei’s victory in Argentina’s presidential election opens a new and uncertain chapter in the South American nation’s convoluted history.

Corporate America meanwhile has been very concerned with the consequences—namely what happens to the food industry as more people take drugs that suppress hunger. The category includes Novo Nordisk’s Ozempic, originally used as a diabetes treatment, and Wegovy, as well as Eli Lilly’s diabetes drug Mounjaro and its Zepbound, which got approved for weight-loss earlier this month. As the holidays arrive, what does this mean for the nation’s annual celebration of dining table-excess? This could end up being a Thanksgiving like no other.
