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 world’s fastest supercomputers
When the Frontier supercomputer came online last year, it marked the dawn of so-called exascale computing, with machines that can execute an exaflop—or a quintillion (1018) floating point operations a second.
Since then, scientists have geared up to make more of these blazingly fast computers: several exascale machines are due to come online in the US and Europe in 2024.
But speed itself isn’t the endgame. Researchers hope to pursue previously unanswerable questions about nature—and to design new technologies in areas from transportation to medicine. Read the full story.

How electricity could clean up transportation, steel, and even fertilizer
“Electrify everything” is a common refrain in climate circles. The basic concept is a simple one: there are some parts of our world that are largely powered directly by fossil fuels, like vehicles or home heating.
Meanwhile, renewables power an increasing fraction of the electrical grid every year. So if we can find ways to hook these fossil-fuel-powered systems up to electricity instead, we’ll be well on our way to real climate action.
People shouting “Electrify everything” often focus on familiar examples like vehicles and homes. But can we electrify steel production? What about fertilizer? What might it mean to actually electrify everything? Read the full story.
Psst: these are just some of the questions our climate reporter Casey Crownhart will be discussing during our second annual ClimateTech conference, taking place at MIT on October 4 and 5. Nab your ticket now!

The big story
Social media is polluting society. Moderation alone won’t fix the problem
We all want to be able to speak our minds online—to be heard by our friends and talk (back) to our opponents. At the same time, we don’t want to be exposed to unpleasant speech.
Technology companies address this conundrum by setting standards for free speech, a practice protected under federal law, hiring in-house moderators to examine individual pieces of content and removing them if posts violate predefined rules.
The approach clearly has problems: harassment, misinformation about topics like public health, and false descriptions of legitimate elections run rampant. But even if content moderation were implemented perfectly, it would still miss a whole host of issues. We need a new strategy: treat social media companies as potential polluters of the social fabric, and directly measure and mitigate the effects their choices have on human populations.
