The Download: attempting to read someone’s mind, and AI weather forecasting

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.

Is it possible to really understand someone else’s mind?

Technically speaking, neuroscientists have been able to read your mind for decades. It’s not easy, mind you. First, you must lie motionless within a hulking fMRI scanner, perhaps for hours, while you watch films or listen to audiobooks.

None of this, of course, can be done without your consent; for the foreseeable future, your thoughts will remain your own, if you so choose. But if you do elect to endure claustrophobic hours in the scanner, the software will learn to generate a bespoke reconstruction of what you were seeing or listening to, just by analyzing how blood moves through your brain.

More recently, researchers have deployed generative AI tools, like Stable Diffusion and GPT, to create far more realistic, if not entirely accurate, reconstructions of films and podcasts based on neural activity.

But as exciting as the idea of extracting a movie from someone’s brain activity may be, it is a highly limited form of “mind reading.” To really experience the world through your eyes, scientists would have to be able to infer not just what film you are watching but also what you think about it, and how it makes you feel. And these interior thoughts and feelings are far more difficult to access. Read the full story.

Google DeepMind’s weather AI can forecast extreme weather faster and more accurately

The news: A new AI model from Google DeepMind could make it easier to predict extreme weather events, helping us to prepare better for natural disasters and help save lives. The model, called GraphCast, was able to predict weather conditions up to 10 days in advance, more accurately and much faster than the current gold standard.

How it works: Traditionally, meteorologists use massive computer simulations to make weather predictions. They are very time consuming to run, because the simulations take into account many physics-based equations and different weather variables. Instead of using physics-based equations, GraphCast bases its predictions on four decades of historical weather data. Read the full story.

Huawei’s 5G chip breakthrough needs a reality check

Later today, Xi Jinping will make his first visit to the US in six years to discuss military issues, trade, and more with Joe Biden in San Francisco. Since that last trip in 2017, a harmonious era in US-China relations ended; we’ve seen a trade war, a pandemic, an ongoing technology rivalry, an off-course spy balloon, and many other tumultuous developments.

Telecom and technology firm Huawei was one of the first Chinese tech companies to receive intense scrutiny and become a target for sanctions driven by national security concerns. Huawei shocked the world in August when it started selling a new flagship phone, the Mate 60 Pro, complete with a new 5G chip, even though the company has been blocked from sourcing 5G chips or working with chip factories outside of China since 2020.

Regulators in DC panicked that the relatively advanced seven-nanometer chip proved the company had somehow circumvented sanctions. But had it really? Read the full story.
