The Download: the oldest corner of the metaverse, and how EV batteries work

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.

Welcome to the oldest part of the metaverse

Today’s headlines treat the metaverse as a hazy dream yet to be built. But if it’s defined as a network of virtual worlds we can inhabit, its oldest corner has been already running for 25 years.

It’s a medieval fantasy kingdom created for the online role-playing game Ultima Online. 

It was the first to simulate an entire world: a vast, dynamic realm where players could interact with almost anything, from fruit on trees to books on shelves.

Ultima Online has already endured a quarter-century of market competition, economic turmoil, and political strife. So what can this game and its players tell us about creating the virtual worlds of the future? Read the full story.

How does an EV battery actually work?

The batteries propelling electric vehicles have quickly become the most crucial component, and expense, for a new generation of cars and trucks.

The vast majority of electric vehicles are powered by lithium-ion batteries, which are also found in smartphones. They can hold high voltage and exceptional charge, making them an efficient, dense form of energy storage.

But while they’re expected to remain dominant in EVs for the foreseeable future, battery developers are working towards lighter, cheaper and more efficient alternatives. Read the full story.

The big story

The messy morality of letting AI make life-and-death decisions

October 2022

In a workshop in the Netherlands, Philip Nitschke is overseeing testing on his new assisted suicide machine. Sealed inside the coffin-sized pod, a person who has chosen to die must answer three questions. The machine will then fill with nitrogen gas, causing the occupant to pass out in less than a minute and die by asphyxiation in around five.

Despite a 25-year campaign to “demedicalize death” through technology, Nitschke has not been able to sidestep the medical establishment fully. A solution could come in the form of an algorithm that Nitschke hopes will allow people to perform a kind of psychiatric self-assessment. 

While his mission may seem extreme—even outrageous—to some, he is not the only one looking to involve technology, and AI in particular, in life-or-death decisions. Read the full story.

+ These preserved ghost ships are seriously spooky.
+ Humankind’s ancient relatives could have been handy with tools millions of years ago.
