Elon Musk has announced the Terafab project, a joint venture between Tesla, SpaceX and xAI, to build the "largest chip manufacturing facility ever." In his usual grandiose fashion, Musk claims Terafab is the next step towards harnessing the power of the sun and creating a "galactic civilization."
Musk, CEO of all three companies, announced plans for the Terafab in a livestream on X. As the name implies, the project's ultimate goal is to produce a terawatt of computing power each year so that it can match the companies' growing demand for chips. Musk explained during the livestream that he's grateful to existing supply chain partners like Samsung, TSMC and Micron, but the current capacity of chip manufacturers only adds up to about two percent to what Tesla and SpaceX needs in terms of future computing power needs.
"We either build the Terafab or we don't have the chips," Musk said during the event. "And we need the chips so we're going to build the Terafab."
The Terafab project, estimated to cost at least $20 billion, will start with the Advanced Technology Fab in Austin, Texas, where Tesla is already headquartered. Musk said that the two types of chips will be produced in the Terafab: one for terrestrial purposes, like to power Full Self-Driving or Optimus robots, and another more high-powered, durable chip to be used in space. If you're wondering what Musk has in store for space, the SpaceX CEO filed an application with the Federal Communications Commission to launch a million satellites to create an "

 iOS 26.4 isn't the major update with new Siri features that we hoped for, but there are some useful quality of life improvements, and a little bit of fun with an AI playlist generator and new emoji characters.

Apple has started providing small security updates to iOS, iPadOS and macOS devices. These are dubbed Background Security Improvements that will offer minor system updates between the larger software updates. According to the company, these are meant to "deliver lightweight security releases for components such as the Safari browser, WebKit framework stack, and other system libraries that benefit from smaller, ongoing security patches between software updates."
These updates should download in the background, as the name implies, although the device will need to be restarted to complete the process. In practice, we found that applying a Background Security Improvement was faster than a typical software update from Apple. On an iPhone, the restart was more of a power cycle taking under a minute compared with the 5 to 10 minutes a standard update takes a device out of commission.
The inaugural Background Security Improvement was released today with a patch for WebKit. These updates will be supported and enabled on devices running iOS 26.1, iPadOS 26.1 and macOS 26.1. Details can be reviewed under the Privacy & Security section of the Settings menu.
