The Download: greener steel, and join us for EmTech 2024
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.
How the auto industry could steer the world toward green steel
Steel scaffolds our world, undergirding buildings and machines. It also presents a major challenge for climate change, as steel production is currently responsible for about 7% of global greenhouse gas emissions.
There’s a growing array of technologies that can produce steel with dramatically lower emissions—though some are still in development, and they often come with a higher price tag.
Finding economical ways to produce the materials we rely on while also cutting emissions is a major challenge for the industrial sector. But since automakers use a lot of steel, they have an opportunity to lead the charge to decarbonize the industry. Here’s how they could do it.

EmTech 2024 is coming
Want to learn more about the technologies that are shaping our lives? Join us for our flagship conference EmTech, held on the MIT Campus from September 30th to October 1st this fall. Take a sneak peek at our jam-packed agenda, which includes:
+ Ray Kurzweil, principal researcher at Google and AI visionary, discussing his latest predictions on artificial general intelligence, singularity, and the infinite possibilities of an AI-integrated world.
+ Riki Banerjee, CTO of brain-computer interface company Synchron, will give us an inside look at the future of minimally invasive brain-computer interfaces that enable humans to use their thoughts to control digital devices.
+ Pete Shadbolt, the cofounder and chief scientific officer of PsiQuantum, which is working to build the biggest US-based quantum computing facility, will explain the rewards and challenges facing quantum tech.
+ Yasmin Green, CEO of Jigsaw, a global security unit within Google, will dive into the secret digital behaviors of Gen Z.

The big story
Quantum computing is taking on its biggest challenge: noise
January 2024
In the past 20 years, hundreds of companies have staked a claim in the rush to establish quantum computing. Investors have put in well over $5 billion so far. All this effort has just one purpose: creating the world’s next big thing.
But ultimately, assessing our progress in building useful quantum computers comes down to one central factor: whether we can handle the noise. The delicate nature of their systems makes them extremely vulnerable to the slightest disturbance, which can generate errors or even stop a quantum computation in its tracks.
In the last couple of years, a series of breakthroughs have led researchers to declare that the problem of noise might finally be on the ropes. Read the full story.
