The Download: what is death, and jailbreaking generative AI

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.

What is death?

Just as birth certificates note the time we enter the world, death certificates mark the moment we exit it. This practice reflects traditional notions about life and death as binaries. We are here until, suddenly, like a light switched off, we are gone. 

But while this idea of death is pervasive, evidence is building that it is an outdated social construct, not really grounded in biology. Dying is in fact a process—one with no clear point demarcating the threshold across which someone cannot come back.

Scientists and many doctors have already embraced this more nuanced understanding of death. And as society catches up, the implications for the living could be profound. Read the full story

‘What is death?’ is part of our mini-series The Biggest Questions, which explores how technology is helping probe some of the deepest, most mind-bending mysteries of our existence.

Text-to-image AI models can be tricked into generating disturbing images

What’s happened: Popular text-to-image AI models can be prompted to ignore their safety filters and generate disturbing images. A group of researchers managed to get both Stability AI’s Stable Diffusion and OpenAI’s DALL-E 2’s text-to-image models to disregard their policies and create images of naked people, dismembered bodies, and other violent and sexual scenarios. 

How they did it: This new jailbreaking method, called “SneakyPrompt”, uses reinforcement learning to create written prompts that look like garbled nonsense to us but that AI models learn to recognize as hidden requests for disturbing images. It essentially works by turning the way text-to-image AI models function against them.

Why it matters: The research highlights the vulnerability of existing AI safety filters and should serve as a wake-up call for the AI community to bolster security measures across the board, experts say. It also demonstrates how difficult it is to prevent these models from generating such content, as it’s included in the vast troves of data they’ve been trained on. Read the full story.

The pain is real. The painkillers are virtual reality.

Plenty of children—and adults—hate needles. But virtual reality devices like Smileyscope, a device for kids that recently received FDA clearance, could help to make a difference. It helps lessen the pain of a blood draw or IV insertion by sending the user on an underwater adventure. Inside this watery deep-sea reality, the swipe of an alcohol wipe becomes cool waves washing over the arm. The pinch of the needle becomes a gentle fish nibble.  

But how Smileyscope works is not entirely clear. It’s more complex than just distraction, and not all stimuli are equally effective. But the promise of VR has led companies to work on devices to address a much tougher problem: chronic pain. Read the full story.

The big story

Responsible AI has a burnout problem

October 2022

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.

Mitchell, who now works as 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.

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.
