It's October in the Midwest, which means it's time for the pinball world to descend on a convention center in Chicagoland for the annual Pinball Expo. Once thought to be an entertainment sector slowly bleeding out, pinball has come back in a big way in recent years. I visited one of Chicago's last old-school manufacturers before heading down the road to see what's new in the silver-ball universe.

Behind the silver ball

Hundreds gathered on a brisk fall Friday morning outside Stern Pinball's headquarters in Elk Grove, Illinois, waiting to enter a Wonka-like wonder factory where piles of raw parts become licensed creations from Jaws to the brand-new Fallout. Stern invited me to tour its offices and factory floor before heading off to the convention in nearby Schaumburg, Illinois.

An early-morning line begins to form outside of Stern HQ as buses of Pinball Expo attendees arrive for tours.

As I stood with my tour group in Stern Pinball's HQ lobby, mouth agape at the dozens of machines lining the walls, we were greeted by the man himself, Gary Stern, who gave us some background on the company's 40-year history. After a stop at Gary's podium, we were ushered to the factory floor entrance, where Stern employee and legendary game designer George Gomez briefed us on the tour rules and answered questions. According to Gomez, "at any given time, Stern controls 90 percent of the current pinball market, and everybody else splits the rest."

As I sat in the cab of the pickup truck and manually rolled down the windows, I closed my eyes and, for the briefest moment, flashed back to opening the windows on a cold, winter day in my dad’s 1975 Ford Ranger to let more cigarette smoke escape. I opened my eyes and looked through the windshield at a wall in the Slate Customer Experience Center studded with bright color chips.

Last week, in a former Tesla store staffed by some former Tesla employees, Slate opened its first showroom. Located in the Fulton Market District just northwest of the Chicago Loop, the Slate Experience Center is a place for would-be buyers to poke around a prototype, check out customization options, buy some Slate merch, and even preorder a new Slate Truck with a $300 deposit.

Designed for the American obsession with pickup trucks, the Slate Truck is a bare-bones electric pickup truck retailing for $24,950. It sports plastic panels, a minimalist interior design sensibility, actual window winders, and a projected range of 205 miles. Ars went for a ride in a Slate Truck over the summer, but we haven't had a chance to shop for one. So I stopped by the Slate Experience Center so I could, er, experience the Slate.

Virtual reality is in a bit of a weird place right now. After a lot of unfulfilled promise in the 1990s, it came back strong with the 2016 release of the Oculus Rift. For a while, it looked like VR, AR, XR, the metaverse, or whatever you wanted to call it, was going to be huge. Mark Zuckerberg was certainly convinced, and even Apple got in on the hype with its Vision Pro.

But by then momentum for alternate realities of every acronym was already in steady decline, and it only dwindled from there. The rate of development of new headsets has slowed, with many companies (including Apple) scaling back or shelving their efforts. While new releases like the Steam Frame and Pimax Dream Air are still happening, many of the most interesting developments in the space these days are on the enthusiast front.

That's right, DIY VR is a thing, and with a couple hundred dollars in components, plus many hours of your time, you too can enter the immersive world of virtual reality while also experiencing the highs and lows of soldering, firmware flashing, and 3D printing. I rode that rollercoaster myself and learned why this is still a decidedly niche movement.

Android was designed for phones, but that hasn't stopped Google from trying to adapt the OS and its apps to larger machines over the years. Googlebooks are just the latest attempt after tablets, Chromebooks, and foldables induced little change in how people interact with Android software. These new Android-powered laptops are designed to pick up where the web-focused ChromeOS left off, offering premium hardware and native support for Android apps.

Google sees Googlebooks as an alternative to Windows and macOS, but these platforms are entrenched with decades of software and UI conventions that keep users locked in. Googlebooks have to offer something very special to steal users away from either of the dominant operating systems.

For devoted Android phone users, there are some cool things in Googlebook OS, but the Android roots of these machines are impossible to miss. Sometimes it feels like using a Chromebook, and sometimes it feels like using a giant phone. It almost never feels like using a premium laptop, and that's the problem.

Safety researchers continue to warn that a large volume of AI-generated explicit content is spreading unchecked, while regulators do little to meaningfully stop it.

This non-consensual content is commonly shared in text and direct messages or stored in private clouds where it’s less likely to be detected or reported, a Google co-authored study of Internet users across the United States, Australia, and the United Kingdom found this July. That’s why the “most critical intervention point” remains at the source: the harmful AI tools used to make the fake sexual images, Google researchers concluded.

Yet red-teaming in recent months suggests that as some of the leading AI image generators from Google and OpenAI become more capable, they may be getting worse at blocking explicit outputs.

No organization in the world operates more robots than Amazon. The company already has more than 1 million robots working in warehouses around the clock to make tens of millions of same-day and one-day package deliveries happen on a daily basis—and Amazon is poised to significantly grow that robotic fleet in the coming years as it establishes new factories to churn out increasingly more capable robot workers.

Despite deploying so many robots, Amazon is also the second-largest corporate employer in the world, with more than 1.5 million full-time and part-time human workers, according to its 2025 annual report. Amazon executives say that the growing robot fleet has eased the burden on its human workforce by taking on the toughest fulfillment center tasks that carry the greatest risks of physical fatigue and injury. But labor advocacy groups and independent researchers point to evidence suggesting that warehouse automation driven by AI is not all upside for the humans who work alongside robots.

“For the last 100 years, most of the automation that we've seen usually happens away from workers—you're taking that high-risk task away from the worker, and you're doing so in a way that is not physically proximate,” Brad Greenwood, professor of business at George Mason University, told Ars. “The rise of collaborative robots really changes that dynamic for two reasons: one is that it is physically proximate, and two, the robot has the ability to dictate the pace of work.”

In July 2010, US Senator Blanche Lincoln (D-Ark.) predicted the rise of prediction markets and the problems they could cause. If not properly regulated, Lincoln warned during Senate proceedings on the Dodd–Frank Wall Street Reform and Consumer Protection Act, prediction markets could evade gambling laws by offering "event contracts" that let people place wagers on sports games.

"It would be quite easy to construct an event contract around sporting events such as the Super Bowl, the Kentucky Derby, and Masters golf tournament," Lincoln, who played a key role in making the law that now regulates prediction markets, told fellow senators. "These types of contracts would not serve any real commercial purpose. Rather, they would be used solely for gambling."

Today, Lincoln is a lobbyist for prediction market Kalshi and has urged the Commodity Futures Trading Commission (CFTC) to allow sports gambling on the markets. The firm she founded has received $480,000 from Kalshi since 2024 in exchange for lobbying Congress and the CFTC for looser regulation of event contracts.

It's no surprise that NASA's new tack toward foreign partnerships—good deals only, please—is challenging preconceived notions of international cooperation in space.

Without a massive budget hike, the US space agency's emphasis on building a Moon Base and winning a competition for lunar real estate and resources with China will inevitably leave lesser priorities behind.

Gone is the Lunar Gateway, a space station that was to be assembled in orbit around the Moon. For the United States, Gateway was an unnecessary distraction and expense as NASA goes all-in on placing a surface station near the Moon's south pole.
