🪴 Last Week in Tech: Raiding World of Warcraft Dungeons with your Thoughts

Anthropic built an AI too dangerous to release
Every week there’s an Anthropic news. Sorry but it is what it is.
Now they developed a new model called Claude Mythos. It’s powerful enough to find zero-day vulnerabilities across every major operating system and browser in the world. All of them.
They’re not releasing it publicly.
Instead they launched Project Glasswing, a closed partnership with Apple, Google, Microsoft, Amazon and Nvidia to use Mythos defensively.
The idea is to find and patch critical vulnerabilities before attackers build something similar and go on the offensive.
US Treasury Secretary Bessent and Fed Chair Powell held an emergency meeting with major banks this week specifically about Mythos. They're trying to lock down financial infrastructure ahead of any potential leak.
OpenAI isn’t far behind. They confirmed this week they’re releasing a dedicated cybersecurity AI product to a limited set of partners in the coming months. Both frontier labs are now explicitly in the arms race between offensive and defensive AI capabilities.
A paralysed veteran raiding World of Warcraft dungeons with his thoughts
Jon Noble is a British Army veteran paralysed from the shoulders down after a car accident in 2004. In December 2025 he became the 18th person to receive a Neuralink N1 brain-computer interface, implanted directly into his motor cortex.
This week he hit 100 days with the chip.
By week three, controlling a cursor felt natural
By day 80 he loaded up World of Warcraft. The first raid was clunky. Then his brain synced with the interface and he describes it as “pure magic.”
He’s now raiding WoW dungeons at full speed, no keyboard, no mouse, only thoughts.
“The N1 didn’t just give me a new way to use a computer. It gave me a new way to live,” he says.
Neuralink is still a clinical trial with a tiny number of participants. It is not a consumer product. But the rate of progress is remarkable.
Scientists just worked out why some people get ALS and dementia and others with the same gene mutation don’t
The most common genetic cause of both is the C9orf72 mutation. Loads of people carry it and never develop either condition. Nobody could explain why.
Case Western Reserve just found the answer: gut bacteria.
Certain microbes produce a toxic sugar that triggers an immune response, which crosses into the brain and starts killing cells. 70% of ALS patients had elevated levels. Only a third of healthy people did.
When researchers reduced the harmful sugars, brain health improved and lifespan extended.
India built a 1,000km quantum network six years early
India’s National Quantum Mission demonstrated a 1,000km quantum communication network this week. One of the longest in the world. Built with indigenous technology by a startup called QNu Labs.
The original timeline was 2,000km in eight years. They hit half that distance in under two years.
Quantum key distribution means the network is physically impossible to intercept. If anyone tries, the quantum state of the signal changes and the receiver knows immediately.
Also, they are inaugurating their first indigenous, open-access quantum computer tomorrow.
Compute is the only thing that matters now
Meta signed a $21B additional compute deal with CoreWeave this week, on top of a prior $14.2B commitment. Anthropic signed a major deal with them too. CoreWeave stock jumped 11% on the news.
Meta’s total capex for 2026 is projected at $115-135 billion. Nearly double last year. All of it AI infrastructure.
Amazon confirmed their cloud AI revenue hit a $15B run rate in Q1. Their custom chips business (Graviton and Trainium) is now doing $20B annually, double the number they cited earlier this year.
Software stocks are getting cooked
The SaaS ETF (IGV) is down 27% year to date.
ServiceNow dropped 8% in a single session this week.
Salesforce led the Dow down.
Datadog off 5%.
The market is repricing every software company that built its moat on complexity.
If Claude can automate the workflows that justify your $50k/year enterprise contract, your revenue multiple collapses. Investors are figuring this out and the sell-off is accelerating.
The companies most at risk are the ones where the core product is a wrapper around human labour doing repetitive knowledge work. So.. most of SaaS.
Scientists watched Alzheimer’s form in real time
For decades we knew copper ions triggered the protein clumping that destroys brain cells. We could see the before and after, just couldn't see the process.
Oregon State built a technique that tracks it second by second as it occurs. They also found a molecule that can grab the copper and reverse the clumping after it starts.
The lead researcher said "with the correct targeting, some of the brain damage might be reversible".
