The Download: what’s next for chips, and climate-tweaking controversy

Plus: how Ukraine built a formidable digitized army

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.

What’s next for the chip industry

The year ahead was already shaping up to be a hard one for semiconductor businesses, which experience cycles of soaring and dwindling demand. The industry was already anticipating declining growth—but geopolitics could present a far bigger challenge.

In recent months, the US has instituted the widest restrictions ever on the kind of chips that can be sold to China. It’s also introduced generous federal subsidies to encourage manufacturers back to the US. Other governments in Europe and Asia have launched similarly protectionist policies.

As these changes continue to take effect in 2023, they will throw a new element of uncertainty into an industry that has long relied on globally distributed supply chains and free trade. Here’s how experts think it will all play out over the next year. Read the full story.

A startup says it’s already started trying to tweak the climate

The news: A startup called Make Sunset claims to have launched weather balloons that may have released reflective sulfur particles in the stratosphere, potentially breaking a controversial barrier in the field of solar geoengineering.

Why it’s controversial: In theory, spraying sulfur and similar particles in sufficient quantities could potentially ease global warming. But scientists have largely avoided doing so, partly because so little is known about the real-world effect of such deliberate interventions.

What’s next: Luke Iseman, the cofounder and CEO of Make Sunsets, acknowledges that it’s a provocative experiment, but says he hopes it will help to nudge us towards the more radical interventions now required to slow climate change. However, experts in the field think such efforts are wildly premature and could have the opposite effect. Read the full story.

The big story

The big new idea for making self-driving cars that can go anywhere

May 2022

When Alex Kendall sat in a car on a small road in the British countryside and took his hands off the wheel back in 2016, it was a small step in a new direction—one that a new bunch of startups bet might be the breakthrough that makes driverless cars an everyday reality.

This was the first time that reinforcement learning—an AI technique that trains a neural network to perform a task via trial and error—had been used to teach a car to drive from scratch on a real road. It took less than 20 minutes for the car to learn to stay on the road by itself, Kendall claims.

These startups are betting that smarter, cheaper tech will let them overtake current market leaders. But is this yet more hype from an industry that’s been drinking its own Kool-Aid for years? Read the full story.
