Reddit users who were unwittingly subjected to an AI-powered experiment have hit back at scientists for conducting research on them without permission – and have sparked a wider debate about such experiments. The social media site Reddit is split into "subreddits" dedicated to a particular community, each with its own volunteer moderators. Members of one subreddit called r/ChangeMyView, because it invites people to discuss potentially contentious issues, were recently informed by the moderators that researchers at the University of Zurich, Switzerland, had been using the site as an online laboratory. The team's experiment seeded more than 1700 comments generated by a variety of large language models (LLMs) into the subreddit, without disclosing they weren't real, to gauge people's reactions. These comments included ones mimicking people who had been raped or pretending to be a trauma counsellor specialising in abuse, among others.

Earlier this month, we heard rumblings that Google had plans to launch a more child-friendly version of its AI chatbot Gemini, and now 9to5Google reports that the tech giant has confirmed in an email to parents that the kids' version of Gemini is officially in the works. Children under the age of 13 will be able to start using Gemini in the coming months via a supervised account, and parents will be able to manage their children's usage via Google's Family Link app. Google says Gemini can help children with homework and creative endeavors like making up stories, but also points out that Gemini can indeed make mistakes. The tech giant wants parents to teach children never to enter personal information into the chatbot, and to think critically about Gemini's answers and always double-check responses. Even though it sometimes talks like one, it can't think for itself or feel emotions," Google writes in the email to parents, who can disable Gemini access for their kids via the Family Link app or website.

Yelp has announced new AI-powered call answering features for restaurants and services as part of its Spring Product Release. With the service, currently under development, the company hopes that "businesses never have to miss a call again." "In this next step of our product transformation, we're continuing to harness AI to unlock the potential of Yelp's rich data in ways that build trust and simplify decision-making -- whether users are hiring a pro or booking a reservation," Yelp's chief product officer, Craig Saldanha, said in a statement. "By grounding our AI in real consumer behavior and business data, we're creating intuitive, transparent features that improve the experience for everyone on Yelp." The AI-powered system "will be fully integrated into Yelp's platform with customizable features and the ability to answer general questions, filter spam, transfer calls when needed, and capture messages."

The current U.S. administration has launched a wara on academia. Indirect costs, or, more accurately, facility and administration expenses, support research but cannot be directly attributed to a specific project, such as lab infrastructure, utilities, and administrative support. These are real costs; the limit, which has since been suspended by courts, is a severe blow to biomedical research in the U.S. Beyond expanding this limit to other agencies, such as the National Science Foundation (NSF), the administration is also reportedly considering slashing NSF's annual budget from approximately US 9 billion down to about US 3– 4 billion. This would deal a devastating blow to academic U.S. research, especially computing research. As statedc by the Computing Research Association (CRA), "NSF budget cuts would put the future of U.S. innovation and security at risk."

Russia has rejected a proposal from Ukraine to extend Russian President Vladimir Putin's unilateral three-day ceasefire as the United States grows increasingly impatient with stalled efforts to find a long-term solution to end the war. Kremlin spokesman Dmitry Peskov confirmed on Tuesday that Moscow had seen Ukrainian President Volodymyr Zelenskyy's offer to extend Putin's brief early May pause in fighting to 30 days. But Peskov said it would be "difficult to enter into a long-term ceasefire" without first clearing up a number of "questions". Zelenskyy had branded Putin's unilateral truce, which will last from May 8 to 10 and coincides with Moscow's celebrations to mark the 80th anniversary of its victory over Nazi Germany in World War II, as an "attempt at manipulation". The Ukrainian leader also questioned why Moscow would not agree to Kyiv's call for a ceasefire lasting at least 30 days and starting immediately.

OpenAI, which spends far more money than it takes in, is trying something new to stanch the bleeding. The company just announced that all users, including on the free tier, can shop from ChatGPT Search. "You can now search for a product, compare options and buy products in ChatGPT," OpenAI said in a press release. Categories currently available include fashion, beauty, home goods and electronics, with expansion to more categories set to come later. The search results you'll obtain are "chosen independently and are not ads," the company promises. The updates are available in 4o and are rolling out to ChatGPT Plus, Pro, Free and even logged-out users.

In at least one crucial way, AI has already won its campaign for global dominance. An unbelievable volume of synthetic prose is published every moment of every day--heaping piles of machine-written news articles, text messages, emails, search results, customer-service chats, even scientific research. Chatbots learned from human writing. Now the influence may run in the other direction. Some people have hypothesized that the proliferation of generative-AI tools such as ChatGPT will seep into human communication, that the terse language we use when prompting a chatbot may lead us to dispose of any niceties or writerly flourishes when corresponding with friends and colleagues.

Duolingo is now going to be "AI-first," the company has announced -- aka it will drop employees in favor of using AI. In a publicly shared email, CEO Luis von Ahn outlined how Duolingo will "gradually stop using contractors to do work that AI can handle." This follows the company's January 2024 decision to cut 10 percent of its contractors, in part because AI could do their tasks. In the email, von Ahn points to Duolingo's "need to create a massive amount of content, and doing that manually doesn't scale. One of the best decisions we made recently was replacing a slow, manual content creation process with one powered by AI. Without AI, it would take us decades to scale our content to more learners. We owe it to our learners to get them this content ASAP."

That's why we've created the AI Hype Index--a simple, at-a-glance summary of everything you need to know about the state of the industry. Take a look at this month's edition of the index here. Despite its ubiquity, AI is seen as anything but a normal technology. There is talk of AI systems that will soon merit the term "superintelligence," and the former CEO of Google recently suggested we control AI models the way we control uranium and other nuclear weapons materials. A recent essay by two AI researchers at Princeton argues that AI is a general-purpose technology whose application might be better compared to the drawn-out adoption of electricity or the internet than to nuclear weapons.

The US House of Representatives has passed the Take It Down Act, a bipartisan bill that criminalizes the "publication of non-consensual, sexually exploitative images," including AI-generated deepfakes that depict "identifiable, real people." It would also compel platforms, such as social networks, to remove those images within 48 hours of being notified. The bill enjoyed overwhelming support in Congress and was cleared for approval by President Trump with a vote of 409 to 2. It passed Senate unanimously in February, and Trump, who previously talked about it while addressing Congress, is expected to sign the bill into law. Nearly every state in the country has its own laws revolving around revenge porn, and there are 20 states that already have laws that cover deepfakes. Take It Down's authors, who include Senator Ted Cruz, explained that those laws "vary in classification of crime and penalty and have uneven criminal prosecution." Victims are also still having a tough time getting their images removed under those laws.
