Generative AI is changing everything. But what’s left when the hype is gone?

It was clear that OpenAI was on to something. In late 2021, a small team of researchers was playing around with a new version of OpenAI’s text-to-image model, DALL-E, an AI that converts short written descriptions into pictures: a fox painted by Van Gogh, perhaps, or a corgi made of pizza. Now they just had to figure out what to do with it.

Nobody could have predicted just how big a splash this product was going to make. The rapid release of other generative models has inspired hundreds of newspaper headlines and magazine covers, filled social media with memes, kicked a hype machine into overdrive—and set off an intense backlash from creators.

The exciting truth is, we don’t really know what’s coming next. While creative industries will feel the impact first, this tech will give creative superpowers to everybody. In the longer term, it could be used to generate designs for almost anything. The problem is, these models still have no idea what they’re doing. Read the full story.

Artists can now opt out of the next version of Stable Diffusion

What’s happened: Artists are now able to opt out of the next version of one of the world’s most popular text-to-image AI generators, Stable Diffusion, the company behind it announced. Creators can search a website called HaveIBeenTrained for their works in the data set that was used to train Stable Diffusion, and select which works they want to exclude from the training data.

Why it’s important: The decision comes amid a heated public debate between artists and tech companies over how text-to-image AI models should be trained. The artist couple who created the website hope that the opt-out service will temporarily compensate for the absence of legislation governing the sector. Read the full story.

Mind-altering substances are being overhyped as wonder drugs

For the past five years or so, barely a week has gone by without a study, comment, or press release about the potential benefits of psychedelic drugs. A growing number of academics, therapists, and companies are interested in the potential of psychedelics like psilocybin and LSD to treat mental-health disorders such as depression, anxiety, PTSD, and substance use disorders, to name a few.

The reputation of psychedelics has been through something of a rollercoaster ride over the last 70 years or so. They went from generating excitement, to instilling fear and mistrust, to experiencing a recent renaissance. But despite the current excitement, the truth is we don’t yet have evidence that psychedelics really are going to change health care, leading to concerns that psychedelics research is “trapped in a hype bubble.” Read the full story.

The big story

How to mend your broken pandemic brain

July 2021

Americans are slowly coming out of the pandemic, but as they reemerge, there’s still a lot of trauma to process. It’s not just our families, our communities, and our jobs that have changed; our brains have changed too. We’re not the same people we were.

During the winter of 2020, more than 40% of Americans reported symptoms of anxiety or depression, double the rate of the previous year. While this fell the following summer, as vaccination rates rose and covid cases fell, many Americans are still struggling with their mental health. Now the question is, can our brains change back? And how can we help them do that? Read the full story.
