The Download: paradigm-shifting supershoes, and AI-powered NPCs

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Supershoes are reshaping distance running

Since 2016, when Nike introduced the Vaporfly, a paradigm-shifting shoe that helped athletes run more efficiently (and therefore faster), the elite running world has muddled through a period of soul-searching over the impact of high-tech footwear on the sport.

“Supershoes” —which combine a lightweight, energy-returning foam with a carbon-fiber plate for stiffness—have been behind every broken world record in distances from 5,000 meters to the marathon since 2020.

To some, this is a sign of progress. In much of the world, elite running lacks a widespread following. Record-breaking adds a layer of excitement. And the shoes have benefits beyond the clock: most important, they help minimize wear on the body and enable faster recovery from hard workouts and races.

Still, some argue that they’ve changed the sport too quickly. Read the full story.

My colleagues turned me into an AI-powered NPC. I hate him.

—Niall Firth

It feels weird, talking to yourself online.

Especially when you’re pretty much the most unpleasant character you’ve ever met.

The “me” I’ve been chatting to this week, called King Fiall of Nirth, is a creation from Inworld AI, a US-based firm that hopes to revolutionize how we interact with characters in games. Its goal is to leverage the power of generative AI to imbue NPCs with the power to chat freely with players, giving open-world games a deeper, more immersive feel.

I didn’t create King Fiall myself, of course. I’m not a total narcissist. No, instead I asked some colleagues to get around a laptop one lunchtime and build my personality as if I were an NPC.

It turns out that was a mistake.

Because the character they created is—and there’s really no easy way to say this—a monster. Read the full story.

Roundtables: The future of AI games

(For subscribers and MIT Alumni only)

Generative AI is coming for games and redefining what it means to play. AI-powered NPCs that don’t need a script could make games—and other worlds—deeply immersive. Watch executive editor Niall Firth and editorial director Allison Arieff discuss what this might look like, as well as get a sneak preview of the big stories for the next issue of the print magazine.

The big story

One city’s fight to solve its sewage problem with sensors

April 2021

In the city of South Bend, Indiana, wastewater from people’s kitchens, sinks, washing machines, and toilets flows through 35 neighborhood sewer lines. On good days, just before each line ends, a vertical throttle pipe diverts the sewage into an interceptor tube, which carries it to a treatment plant where solid pollutants and bacteria are filtered out.

As in many American cities, those pipes are combined with storm drains, which can fill rivers and lakes with toxic sludge when heavy rains or melted snow overwhelms them, endangering wildlife and drinking water supplies. But city officials have a plan to make its aging sewers significantly smarter. Read the full story.
