The Download: brain implant removal, and Nvidia’s AI payoff

Plus: Neuralink has been cleared to start clinical trials in humans

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.

A brain implant changed her life. Then it was removed against her will.

Sticking an electrode inside a person’s brain can do more than treat a disease. Take the case of Rita Leggett, an Australian woman whose experimental brain implant designed to help people with epilepsy changed her sense of agency and self. 

Leggett told researchers that she “became one” with her device. It helped her to control the unpredictable, violent seizures she routinely experienced, and allowed her to take charge of her own life. So she was devastated when, two years later, she was told she had to remove the implant because the company that made it had gone bust.

The removal of this implant, and others like it, might represent a breach of human rights, ethicists say in a paper published earlier this month. And the issue will only become more pressing as the brain implant market grows in the coming years and more people receive devices like Leggett’s. Read the full story.

The big story

 Yann LeCun has a bold new vision for the future of AI

June 2022

Around a year and a half ago, Yann LeCun realized he had it wrong. 

LeCun, who is chief scientist at Meta’s AI lab and a professor at New York University, is one of the most influential AI researchers in the world. He had been trying to give machines a basic grasp of how the world works—a kind of common sense—by training neural networks to predict what was going to happen next in video clips of everyday events. But guessing future frames of a video pixel by pixel was just too complex. He hit a wall.

Now, after months figuring out what was missing, he has a bold new vision for the next generation of AI, which he thinks will one day give machines the common sense they need to navigate the world. But his vision is far from comprehensive; indeed, it may raise more questions than it answers. Read the full story.
