Voice cloning is becoming easier, faster and more convincing. Artificial Intelligence makes it possible to change the age of an actor’s voice, translate words into any language, and replace a voice lost through illness. But it’s also increasingly being used by criminals to impersonate a loved one, extort money or compromise bank accounts. It’s changing how we communicate with each other and how we trust each other. And experts say we’re already at the point where AI voice cloning can be used for real time conversations. So how are the U.S., the U.K. and Europe handling regulation of this rapidly-evolving new technology?

About 170 million U.S. users could be TikTokless as soon as Jan. 19. Early this month, a federal appeals court upheld a law that could ban the very popular short-form video app unless its Chinese owners agree to sell it. They have a willing buyer, though, in billionaire Frank McCourt, who has assembled a consortium of investors ready to put down more than $20 billion. He’s the founder of the internet reform initiative Project Liberty. You may also know him as a real estate developer who once owned the Los Angeles Dodgers.

The artificial intelligence boom and its hunger for electricity has brought a surge of interest in nuclear power. Microsoft, for instance, made a deal to restart the Three Mile Island plant in Pennsylvania, while Google and Amazon have invested in companies developing small, modular reactors. The Joe Biden administration’s Department of Energy aims to triple nuclear energy capacity by 2050, but the sector will need a lot more workers to make that happen. By some estimates there’s a gap of more than 200,000 jobs to fill over the next decade. Marketplace’s Meghan McCarty Carino spoke with Craig Piercy, CEO of the American Nuclear Society, to learn more about the hunt for talent.
