The Download: iRobot privacy scandal, and AI that makes images

Plus: China's funeral parlors are becoming overwhelmed

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.

Roomba testers feel misled after intimate images ended up on Facebook

When Greg unboxed a new robot vacuum cleaner in December 2019, he thought he knew what he was getting into. As a beta-tester, he anticipated allowing the preproduction test version of iRobot’s Roomba J series device to roam around his house, collect data to help improve its artificial intelligence, and provide feedback about his user experience

But what Greg didn’t know—and does not believe he consented to—was that iRobot would share test users’ data in a sprawling, global data supply chain, where everything (and everyone) captured by the devices’ cameras could be seen by low-paid contractors.

Nearly a dozen iRobot testers have come forward in the weeks since MIT Technology Review published an investigation into how the company uses images captured from inside real homes to train its AI. They feel misled by the company’s failure to adequately protect their data, and have been left wondering where the accountability actually lies. Read the full story.

TR10: AI that makes images

When OpenAI released its text-to-image AI model DALL-E in 2021, it paved the way for other programs designed to take a short description of pretty much anything, and spit out a picture of what you asked for in seconds.

Yet the biggest game-changer was Stable Diffusion, an open-source text-to-image model released for free by UK-based startup Stability AI in August, and, crucially, able to run on a (good) home computer.

Nothing else in AI grabbed people’s attention more last year—for the best and worst reasons. Now we wait to see what lasting impact these tools will have on creative industries—and the entire field of AI. Read more about the promises—and dangers—of AI models that create images on demand.

Next: read our senior AI editor Will Douglas Heaven’s feature about how generative AI is changing everything, and what’s likely to be left when the hype dies down. 

AI that makes images is the first of our 10 Breakthrough Technologies, which we’ll be showcasing one-by-one in The Download every day. You can check out the rest of the list for yourself, and we’d love to hear your thoughts on what should make our final 11th technology. Vote in our poll to make your voice heard.

This biotech startup says mice live longer after genetic reprogramming

The news: A small biotech company claims it has used a technology called reprogramming to rejuvenate old mice and extend their lives, a result suggesting that one day older people could have their biological clocks turned back with an injection—literally becoming younger.

The details: The life-extension claim in rodents, made by Rejuvenate Bio, a San Diego biotech company, appears in a preprint paper on the website BioRxiv and hasn’t been peer reviewed.

What to think: The reprogramming technique, which involves resetting cells to a younger state, has been winning hundreds of millions in investment as a potential elixir of youth. Scientists have previously shown that it works on single cells in the laboratory. Despite this startup’s announcement, it’s still unclear if the rejuvenation effect works in living animals too.

The big story

How big science failed to unlock the mysteries of the human brain

August 2021

In September 2011, Columbia University neurobiologist Rafael Yuste and Harvard geneticist George Church made a not-so-modest proposal: to map the activity of the entire human brain at the level of individual neurons and detail how those cells form circuits.

That knowledge could be harnessed to treat brain disorders like Alzheimer’s, autism, schizophrenia, depression, and traumatic brain injury, and would help answer one of the great questions of science: How does the brain bring about consciousness? 

A decade on, the US project has wound down, and the EU project faces its deadline to build a digital brain. So have we begun to unwrap the secrets of the human brain? Or have we spent a decade and billions of dollars chasing a vision that remains as elusive as ever? Read the full story.

We can still have nice things

A place for comfort, fun and distraction in these weird times. (Got any ideas? Drop me a line or tweet 'em at me.)

+ This sweet watercolor cat is just lovely.
