Elon Musk posted on X that Tesla will be restarting work on Dojo3, the third generation of its in-house supercomputer project. The Dojo team had been disbanded last year as the company prioritized the AI chips that run on board Tesla vehicles. Musk said the company is returning to the project “now that the AI5 chip design is in good shape.”

The purpose of the Dojo project is to process video recordings and other data from Tesla vehicles and use that to train the “neural net” behind the company’s Full Self-Driving software. Last year, however, Musk posted on X that “It doesn’t make sense for Tesla to divide its resources and scale two quite different AI chip designs. The Tesla AI5, AI6 and subsequent chips will be excellent for inference and at least pretty good for training. All effort is focused on that.”

The AI chips Musk is referring to are ones developed for running FSD onboard Tesla vehicles and are not optimized for training. The AI6 chips will be made by Samsung in the company’s Texas factory, after it struck a $16 billion agreement with Tesla.

Musk has also claimed a lot of things over the years, and many of those assertions either were misrepresentations or simply didn’t pan out. Working against this chip project: Musk said that Dojo3 will be “space-based AI compute,” as he and others believe that data centers in orbit are a superior alternative to the land-based behemoths currently being built. The idea is that space provides easier access to the sun’s energy, and the cold temperatures there might greatly reduce the power needed, among other benefits. While it’s an increasingly popular if entirely speculative idea, experts have their doubts.

Meta’s Threads is pulling further ahead of Elon Musk’s X on mobile, based on recent estimates from analytics firm Similarweb, Forbes reports. In the first stretch of January, Threads averaged roughly 143 million daily active users worldwide on mobile devices, compared with about 126 million for X.

Similarweb’s year-over-year snapshot shows Threads growing sharply, up 37.8 percent year-over-year, while X’s daily mobile audience fell 11.9 percent across the same period. The picture is more mixed in the US, where X still holds a narrow edge on mobile. Similarweb data puts X at about 21.2 million daily active US mobile users in early January versus roughly 19.5 million for Threads.

However, Threads’ US mobile usage has risen substantially faster over the past year, surging almost 42 percent to X’s 18 percent. X remains far larger on desktop, where it draws around 150 million daily users or visits worldwide, while Threads’ web presence sits at just 9 million.

Forbes also reported on Similarweb data for Bluesky, another competing text-based platform started by Twitter founder Jack Dorsey. Dorsey left the board in the summer of 2024, later telling Pirate Wires he believed Bluesky was “literally repeating all the mistakes we made as a company,” in reference to Twitter. The social network opened registrations in 2024, and sits now with a daily mobile user base of 3.6 million, which Similarweb says is down 44.4 percent year-over-year.

X has found itself in hot water yet again over xAI’s Grok chatbot, which was altering pictures of women on the platform to create lewd images at the request of users without the consent of those pictured. In some cases, the chatbot also altered the images of underage girls. The uproar in response led the company to shut off image generation for nonsubscribers and place firmer guardrails on what types of images can be generated. The delayed action came after weeks of Grok creating tens of thousands of these images, and after the Attorney General of California launched an investigation.

If you weren’t able to shut down your Windows 11 device recently, Microsoft has rolled out an emergency fix addressing a couple of critical bugs that popped up with its latest January 2026 Windows security update. The latest “out-of-band” update repairs an issue for some Windows 11 devices that would only restart when users tried to shut down or hibernate. The same update restores the ability for Windows 10 and Windows 11 users to log into their devices via remote connection apps.

Microsoft said the inability to shut down or hibernate affected Windows 11 devices using Secure Launch, a security feature that protects a computer from firmware-level attacks during startup. As for the remote connection issue, Microsoft explained in its Known issues page that credential prompt failures were responsible when users tried to log in remotely to affected Windows 10 and 11 devices.

According to WindowsLatest, some lingering issues with the January 2026 Windows security update are still affecting users, like seeing blank screens or Outlook Classic crashing. Back in October, Microsoft had to issue another emergency fix for Windows 11 related to the Windows Recovery Environment. For those still hesitant to upgrade to Windows 11, Microsoft is allowing you to squeeze some more life out of Windows 10 by enrolling in Extended Security Updates.
