The Download: a humanoid cleans house and Samsung builds for the AI boom

Plus: Almost $2.5 trillion has been wiped off tech stocks.

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.

I watched a humanoid robot clean my apartment. It felt like a taste of the future.

—Grace Huckins

When I saw an X post about a new humanoid-robot cleaning service in San Francisco, I immediately signed up for the waitlist. I wanted my apartment to feel like The Jetsons, even if just for an hour.

The device that arrived at my building belongs to Tau Robotics, a local startup. Its long-term goal is to make autonomous cleaning robots a reality, but the technology isn’t quite there yet. For now, humans pilot the robots remotely, watching them work through onboard cameras.

There were some unexpected challenges along the way, but also moments that felt like a glimpse of the future.

A visit to Samsung’s massive new semiconductor hub

Generative AI models depend on stacks of specialized memory chips. To meet soaring demand, Samsung is building a vast new semiconductor manufacturing campus in Pyeongtaek, South Korea.

I visited the sprawling campus south of Seoul, where three fabs already operate around the clock, a fourth is coming online, and thousands of workers are racing to build a fifth.

Step inside the vast chipmaking complex powering the AI boom.

How a couple of ski bums built the internet’s best weather app

The best snow-forecasting app for skiers isn’t a federally-funded service or a big-name brand. It’s OpenSnow, a startup that uses government data, its own AI models, and decades of alpine-life experience to deliver the best predictions out there.

The app proved especially vital last winter, one of the weirdest on record. It even made microcelebrities of its forecasters, who sift through reams of data to write “Daily Snow” reports for locations around the world.
