AI image generator Midjourney blocks porn by banning words about the human reproductive system

The news: The popular AI image generator Midjourney bans a wide range of words about the human reproductive system from being used as prompts, MIT Technology Review has discovered. 

What’s included? The list of banned words seem to skew predominantly female, including terms such as “placenta,” “fallopian tubes,” and “mammary glands.” The company says it’s banning these words as a stopgap measure to prevent people from generating shocking or gory  content while it “improves things on the AI side.” 

Why it matters: Midjourney’s crude banning of prompts relating to reproductive biology highlights how tricky it is to moderate content around generative AI systems. It also demonstrates how the tendency for AI systems to sexualize women extends all the way to their internal organs. Read the full story.

How your brain data could be used against you

Our senior biotech reporter Jessica Hamzelou has been in Lisbon, Portugal this week to attend  a scientific conference on brain stimulation. Neuroscientists, brain surgeons, psychiatrists, and ethicists gathered to discuss how to best use the technologies that use magnetic or electrical pulses to change the way our brains work.

We’re still getting to grips with how these technologies work, but in the meantime, some are generating huge amounts of data about individuals’ brains. There’s a chance this data could be used against people in a court of law, making it vital that we start thinking about these uses, and how to protect brain data, now. Read the full story.

The big story

The world is moving closer to a new cold war fought with authoritarian tech

September 2022

Despite President Biden’s assurances that the US is not seeking a new cold war, one is brewing between the world’s autocracies and democracies—and technology is fueling it.

Authoritarian states are following China’s lead and are trending toward more digital rights abuses by increasing the mass digital surveillance of citizens, censorship, and controls on individual expression.

And while democracies also use massive amounts of surveillance technology, it’s the tech trade relationships between authoritarian countries that’s enabling the rise of digitally enabled social control. Read the full story.
