In recent months, a new class of agents has arrived on the scene: ones built using large language models. Any action that can be captured by text—from playing a video game using written commands to running a social media account—is potentially within the purview of this type of system.

LLM agents don’t have much of a track record yet, but to hear CEOs tell it, they will transform the economy—and soon. Despite that, like chatbot LLMs, agents can be chaotic and unpredictable. Here’s what could happen as we try to integrate them into everything.

Lithium-ion batteries have some emerging competition: Sodium-based alternatives.

Sodium is more abundant on Earth than lithium, and batteries that use the material could be cheaper in the future. Building a new battery chemistry is difficult, mostly because lithium is so entrenched. But, as I’ve noted before, this new technology has some advantages in nooks and crannies.

I’ve been following sodium-ion batteries for a few years, and we’re starting to see the chemistry make progress. Let’s talk about what’s new for sodium batteries, and what it’ll take for them to really break out.

Next slide, please: A brief history of the corporate presentationPowerPoint is everywhere. It’s used in religious sermons; by schoolchildren preparing book reports; at funerals and weddings. In 2010, Microsoft announced that PowerPoint was installed on more than a billion computers worldwide.

But before PowerPoint, 35-millimeter film slides were king. They were the only medium for the kinds of high-impact presentations given by CEOs and top brass at annual meetings for stockholders, employees, and salespeople.

Known in the business as “multi-image” shows, these presentations required a small army of producers, photographers, and live production staff to pull off. Read this story to delve into the fascinating, flashy history of corporate presentations.
