Facebook CEO Mark Zuckerberg said the social network could put deepfakes into a “completely different category.” His comments at the Aspen Ideas Festival came in the wake of altered video of House Speaker Nancy Pelosi, which was widely shared on Facebook. Axios had a good summary of all his comments.

Zuckerberg has been getting clobbered by politicians and the media for two years for everything from election manipulation to fake news unfolding on his platform. He knows the pummeling may only intensify with 2020 heating up. Zuckerberg also said Facebook is rethinking its handling of deepfake videos, and said it might make sense to treat them differently from other “false news,” as Facebook calls fake news. Zuckerberg said it’s worth asking whether deepfakes are a “completely different category,” and said developing a policy on these videos is “really important” as AI grows more sophisticated.

Can anywhere in the U.S. challenge Silicon Valley, and San Franciso in particular, to become America’s next tech hub? Economist Tyler Cowen thinks he has the answer. He puts the case for LA in his latest Bloomberg column.

First, consider the virtues of the Los Angeles area. It has splendid weather — warmer and sunnier than San Francisco — and a deep pool of talent. It is America’s second-largest city, with many nice neighborhoods to choose from (some of them, to the east, even affordable). It even has a subway, albeit an underdeveloped one. I would argue it has much better food, and of course a much larger and more diverse entertainment scene. You might reasonably conclude that top talent might prefer to live in or near Los Angeles rather than the Bay Area.
