Once the globe’s largest festival, World’s Fairs provided a glimpse into inventors’ newest creations, technologies, and human-contrived feats. The 1893 Chicago World’s Fair alone debuted electric irons, sewing machines, and laundry machines, along with the Ferris Wheel and Thomas Edison’s Kinetoscope, an early device for displaying motion pictures. So why do we no longer gather at massive exhibitions to show off our latest and greatest inventions? And what does the rise and fall of the World’s Fair tell us about the way technology and society are changing?

Making one’s home “smart” may appear to be a logical step for modern dwellings, but with virtual assistants triggered by voice prompts, refrigerators that sense when your food is running low, and vacuum cleaners that zip around your home crashing into walls, we have substituted the home of the past for something altogether different. But is the smart home actually smart? And, if it’s not there yet, what could do the trick?

Apple’s early App Store ads famously proclaimed, “There’s an app for that”—anything you wanted to do on your phone, the company insisted, you could do through an app. That marketplace ethos still holds today. But when smartphones came to China, there was just one app that really mattered—WeChat, the self-styled “superapp.” In China, people use WeChat for just about everything, so why did the US and Chinese embrace such different mobile ecosystems? And why is the dream of building a superapp in the West so persistent?

ChatGPT isn’t always right. In fact, it’s often very wrong, giving faulty biographical information about a person or whiffing on the answers to simple questions. But instead of saying it doesn’t know, ChatGPT often makes stuff up. Chatbots can’t actually lie, but researchers sometimes call these untruthful performances “hallucinations”—not quite a lie, but a vision of something that isn’t there. So, what’s really happening here and what does it tell us about the way that AI systems err?

Everywhere you go, there’s plastic: plastic water bottles, plastic coffee cups, plastic grocery bags... And recycling plastic is notoriously tricky—what do any of those little numbers even mean on the bottom of a container? We’ve long known that single-use plastics are a problem, but why is it so often the duty of consumers to do something about it? And if producers ultimately do start to take real action, how can they make a dent in this pressing environmental problem?

In the US, voting is seen as a civic duty. It’s voluntary, but it’s an act of patriotism and a democratic responsibility. But there are many barriers to voting—one might have to take off from work, find childcare, or travel long distances to cast a ballot. Wouldn’t voting online instantly expand access to millions of people? Perhaps, but only if we can build a system that’s secure enough to handle it.
