The Download: the human toll of ethical AI, and lab-grown meat


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.

Responsible AI has a burnout problem

Margaret Mitchell had been working at Google for two years before she realized she needed a break. Only after she spoke with a therapist did she understand the problem: she was burnt out. She ended up taking medical leave because of stress.

Mitchell, who now works as an AI researcher and chief ethics scientist at the AI ​​startup Hugging Face, is far from alone in her experience. Burnout is becoming increasingly common in responsible-AI teams, who are unlikely to receive the same levels of support as colleagues who specialize in content moderation, although the work can be just as psychologically draining.

All the practitioners MIT Technology Review interviewed spoke enthusiastically about their work: it is fueled by passion, a sense of urgency, and the satisfaction of building solutions for real problems. But that sense of mission can be overwhelming without the right support. Read the full story.

Will lab-grown meat reach our plates?

Would you eat lab-grown meat? Plenty of companies have set out to generate meat products from muscle and fat cells cultured in vats—around 80 at the last count. The promise is huge: it could allow us to cut back on intensive animal farming , which can be brutal and inhumane, and to sidestep animal agriculture’s destructive effects on the environment.

But whether these companies can deliver on that promise is another matter entirely. And even if companies succeed in bringing a cheap cultured-meat product to market, would anyone eat it? Read the full story.

The big story

Aging clocks aim to predict how long you’ll live

April 2022

Age is much more than the number of birthdays you’ve clocked. Stress, sleep, and diet all influence how our organs cope with the wear and tear of everyday life. Factors like these might make you age faster or slower than people born on the same day. That means your biological age could be quite different from your chronological age—the number of years you’ve been alive.

Your biological age is likely a better reflection of your physical health and even your own mortality than your chronological age. But calculating it isn’t nearly as straightforward. Scientists have spent the last decade developing tools called aging clocks that assess markers in your body to reveal your biological age.

The big idea behind aging clocks is that they’ll essentially indicate how much your organs have degraded, and thus predict how many healthy years you have left. Among the hundreds of aging clocks developed in the last decade, though, accuracy varies widely. And researchers are still grappling with a vital question: What does it mean to be biologically young?
