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.
The looming crackdown on AI companionship
As long as there has been AI, there have been people sounding alarms about what it might do to us: rogue superintelligence, mass unemployment, or environmental ruin. But another threat entirely—that of kids forming unhealthy bonds with AI—is pulling AI safety out of the academic fringe and into regulators’ crosshairs.
This has been bubbling for a while. Two high-profile lawsuits filed in the last year, against Character.AI and OpenAI, allege that their models contributed to the suicides of two teenagers. A study published in July, found that 72% of teenagers have used AI for companionship. And stories about “AI psychosis” have highlighted how endless conversations with chatbots can lead people down delusional spirals.
It’s hard to overstate the impact of these stories. To the public, they are proof that AI is not merely imperfect, but harmful. If you doubted that this outrage would be taken seriously by regulators and companies, three things happened this week that might change your mind.

Meet the designer of the world’s fastest whole-genome sequencing method
Every year, MIT Technology Review selects one individual whose work we admire to recognize as Innovator of the Year. For 2025, we chose Sneha Goenka, who designed the computations behind the world’s fastest whole-genome sequencing method. Thanks to her work, physicians can now sequence a patient’s genome and diagnose a genetic condition in less than eight hours—an achievement that could transform medical care.
Register here to join an exclusive subscriber-only Roundtable conversation with Goenka, Leilani Battle, assistant professor at the University of Washington, and our editor in chief Mat Honan at 1pm ET on Tuesday September 23.

One more thing
Robots are bringing new life to extinct species
In the last few years, paleontologists have developed a new trick for turning back time and studying prehistoric animals: building experimental robotic models of them.
In the absence of a living specimen, scientists say, an ambling, flying, swimming, or slithering automaton is the next best thing for studying the behavior of extinct organisms. Here are four examples of robots that are shedding light on creatures of yore.
