What it means when AI helps solve complex math problems

Reddit announced it will soon require users to log in to see much of the helpful human-generated content on its site. Why? Because traffic, and thus advertising, has taken a hit since AI started summarizing its data.It's the latest development to threaten the old model of the open internet, says Sarah Gilbert, who researches online communities at the Citizens and Technology Lab at Cornell and is also active in r/askhistorians. She says the new login requirement puts up a wall between humans on the internet and is likely to discourage future contributions to the site.More on this:“Reddit moves to logged-in experience as AI eats search” from Axios“AI Is Killing Wikipedia’s Human Traffic” from Gizmodo

The message that Americans have no love for AI data centers rang out loud and clear in the midterms, with dozens of jurisdictions voting to stop their construction and electing governors who oppose them.Where they are still allowed, it's likely we'll see some concessions from data center developers — like community benefit agreements. These agreements have been used for decades for big building projects like transit or sports arenas.Late last year, the city of Lancaster, Pennsylvania, signed one of the first major CBAs with data center developers.Devashree Saha, director of the U.S. Clean Energy Economy Program at the World Resources Institute, explains how the agreement came together and where it might fall short.More on this After the midterms, a bigger clash over data centers could be coming — from Tech CrunchOpenAI pledges no NDAs, protection from power costs in data center deals — from Seeking AlphaPowering Progress: How Community Benefits Agreements Can Drive Responsible Data Center Development — from the World Resources Institute

Voters have made their dissatisfaction quite clear with the tech status quo. And it sounds like the Democrats gearing up to take power in the House and Senate might actually do something about that.Plus, Big Tech spent big on races in this election, but didn't get a whole lot of bang for their buck. But first, a tech issue that was actually on the ballot: data centers. More than 40 jurisdictions across 10 states voted to put them on ice. However, Harwood, North Dakota, gave them the green light. Paresh Dave, senior writer at Wired, joins Marketplace’s Meghan McCarty Carino to explain more about all this on this week’s “Tech Bytes: Week in Review.”More on this:“America got the anti-data-center wave it voted for.

OpenAI's new teen-appropriate version of ChatGPT may not be living up to its promises, according to an independent evaluation. The new mode is supposed to have stronger guardrails for sensitive topics, automatic parental alerts and a study tool that won't just give kids the answers to their homework.But the nonprofit Common Sense Media evaluated the tool and found it poses "unacceptable risks." Tom Siegel leads the Youth Safety Institute at Common Sense and tested about 4,000 prompts using fake teen accounts. He spoke with Meghan McCarty Carino about his findings.More on this:“ChatGPT for Teens Poses Unacceptable Risk to Kids, Common Sense Media Finds” from Common Sense Media
