How the Supreme Court ruling on Section 230 could end Reddit as we know it


But another big issue is at stake that has received much less attention: depending on the outcome of the case, individual users of sites may suddenly be liable for run-of-the-mill content moderation. Many sites rely on users for community moderation to edit, shape, remove, and promote other users’ content online—think Reddit’s upvote, or changes to a Wikipedia page. What might happen if those users were forced to take on legal risk every time they made a content decision? 

In short, the court could change Section 230 in ways that won’t just impact big platforms; smaller sites like Reddit and Wikipedia that rely on community moderation will be hit too, warns Emma Llansó, director of the Center for Democracy and Technology’s Free Expression Project. “It would be an enormous loss to online speech communities if suddenly it got really risky for mods themselves to do their work,” she says. 

In an amicus brief filed in January, lawyers for Reddit argued that its signature upvote/downvote feature is at risk in Gonzalez v. Google, the case that will reexamine the application of Section 230. Users “directly determine what content gets promoted or becomes less visible by using Reddit’s innovative ‘upvote’ and ‘downvote’ features,” the brief reads. “All of those activities are protected by Section 230, which Congress crafted to immunize Internet ‘users,’ not just platforms.” 

At the heart of Gonzalez is the question of whether the “recommendation” of content is different from the display of content; this is widely understood to have broad implications for recommendation algorithms that power platforms like Facebook, YouTube, and TikTok. But it could also have an impact on users’ rights to like and promote content in forums where they act as community moderators and effectively boost some content over other content. 

Reddit is questioning where user preferences fit, either directly or indirectly, into the interpretation of “recommendation.” “The danger is that you and I, when we use the internet, we do a lot of things that are short of actually creating the content,” says Ben Lee, Reddit’s general counsel. “We’re seeing other people’s content, and then we’re interacting with it. At what point are we ourselves, because of what we did, recommending that content?” 

Reddit currently has 50 million active daily users, according to its amicus brief, and the site sorts its content according to whether users upvote or downvote posts and comments in a discussion thread. Though it does employ recommendation algorithms to help new users find discussions they might be interested in, much of its content recommendation system relies on these community-powered votes. As a result, a change to community moderation would likely drastically change how the site works.  

“Can we [users] be dragged into a lawsuit, even a well-meaning lawsuit, just because we put a two-star review for a restaurant, just because like we clicked downvote or upvote on that one post, just because we decided to help volunteer for our community and start taking out posts or adding in posts?” Lee asks. “Are [these actions] enough for us to suddenly become liable for something?”

An “existential threat” to smaller platforms 

Lee points to a case in Reddit’s recent history. In 2019, in the subreddit r/Screenwriting, users started discussing screenwriting competitions they thought might be scams. The operator of those alleged scams went on to sue the moderator of r/Screenwriting for pinning and commenting on the posts, thus prioritizing that content. The Superior Court of California in LA County excused the moderator from the lawsuit, which Reddit says was due to Section 230 protection. Lee is concerned that a different interpretation of Section 230 could leave moderators, like the one in r/Screenwriting, significantly more vulnerable to similar lawsuits in the future.

The Download: AI films, and the threat of microplastics

Welcome to the new surreal. How AI-generated video is changing film.


The Frost nails its uncanny, disconcerting vibe in its first few shots. Vast icy mountains, a makeshift camp of military-style tents, a group of people huddled around a fire, barking dogs. It’s familiar stuff, yet weird enough to plant a growing seed of dread. There’s something wrong here.

Welcome to the unsettling world of AI moviemaking. The Frost is a 12-minute movie from Detroit-based video creation company Waymark in which every shot is generated by an image-making AI. It’s one of the most impressive—and bizarre—examples yet of this strange new genre. Read the full story, and take an exclusive look at the movie.

Microplastics are everywhere. What does that mean for our immune systems?

Microplastics are pretty much everywhere you look. These tiny pieces of plastic pollution, less than five millimeters across, have been found in human blood, breast milk, and placentas. They’re even in our drinking water and the air we breathe.

Given their ubiquity, it’s worth considering what we know about microplastics. What are they doing to us? 

The short answer is: we don’t really know. But scientists have begun to build a picture of their potential effects from early studies in animals and clumps of cells, and new research suggests that they could affect not only the health of our body tissues, but our immune systems more generally.

Microplastics are everywhere. What does that mean for our immune systems?


Here, bits of plastic can end up collecting various types of bacteria, which cling to their surfaces. Seabirds that ingest them not only end up with a stomach full of plastic—which can end up starving them—but also get introduced to types of bacteria that they wouldn’t encounter otherwise. It seems to disturb their gut microbiomes.

There are similar concerns for humans. These tiny bits of plastic, floating and flying all over the world, could act as a “Trojan horse,” introducing harmful drug-resistant bacteria and their genes, as some researchers put it.

It’s a deeply unsettling thought. As research plows on, hopefully we’ll learn not only what microplastics are doing to us, but how we might tackle the problem.

It is too simplistic to say we should ban all plastic. But we could do with revolutionizing the way we recycle it, as my colleague Casey Crownhart pointed out in an article published last year. 

We can use sewage to track the rise of antimicrobial-resistant bacteria, as I wrote in a previous edition of the Checkup. At this point, we need all the help we can get …

… which is partly why scientists are also exploring the possibility of using tiny viruses to treat drug-resistant bacterial infections. Phages were discovered around 100 years ago and are due a comeback!

Our immune systems are incredibly complicated. And sex matters: there are important differences between the immune systems of men and women, as Sandeep Ravindran wrote in this feature, which ran in our magazine issue on gender.

Welcome to the new surreal. How AI-generated video is changing film.


Fast and cheap

Artists are often the first to experiment with new technology. But the immediate future of generative video is being shaped by the advertising industry. Waymark made The Frost to explore how generative AI could be built into its products. The company makes video creation tools for businesses looking for a fast and cheap way to make commercials. Waymark is one of several startups, alongside firms such as Softcube and Vedia AI, that offer bespoke video ads for clients with just a few clicks.

Waymark’s current tech, launched at the start of the year, pulls together several different AI techniques, including large language models, image recognition, and speech synthesis, to generate a video ad on the fly. Waymark also drew on its large data set of non-AI-generated commercials created for previous customers. “We have hundreds of thousands of videos,” says CEO Alex Persky-Stern. “We’ve pulled the best of those and trained it on what a good video looks like.”

To use Waymark’s tool, which it offers as part of a tiered subscription service starting at $25 a month, users supply the web address or social media accounts for their business, and it goes off and gathers all the text and images it can find. It then uses that data to generate a commercial, using OpenAI’s GPT-3 to write a script that is read aloud by a synthesized voice over selected images that highlight the business. A slick minute-long commercial can be generated in seconds. Users can edit the result if they wish, tweaking the script, editing images, choosing a different voice, and so on. Waymark says that more than 100,000 people have used its tool so far.

The trouble is that not every business has a website or images to draw from, says Parker. “An accountant or a therapist might have no assets at all,” he says. 

Waymark’s next idea is to use generative AI to create images and video for businesses that don’t yet have any—or don’t want to use the ones they have. “That’s the thrust behind making The Frost,” says Parker. “Create a world, a vibe.”

The Frost has a vibe, for sure. But it is also janky. “It’s not a perfect medium yet by any means,” says Rubin. “It was a bit of a struggle to get certain things from DALL-E, like emotional responses in faces. But at other times, it delighted us. We’d be like, ‘Oh my God, this is magic happening before our eyes.’”

This hit-and-miss process will improve as the technology gets better. DALL-E 2, which Waymark used to make The Frost, was released just a year ago. Video generation tools that generate short clips have only been around for a few months.  

The most revolutionary aspect of the technology is being able to generate new shots whenever you want them, says Rubin: “With 15 minutes of trial and error, you get that shot you wanted that fits perfectly into a sequence.” He remembers cutting the film together and needing particular shots, like a close-up of a boot on a mountainside. With DALL-E, he could just call it up. “It’s mind-blowing,” he says. “That’s when it started to be a real eye-opening experience as a filmmaker.”
