Five things that mattered
The story with the most sources from each topic.
- Policy & Law
Linked Gmail and Photos data can now shape Google ads
Google changed its privacy policy on October 16, 2026.
Why it matters: Google’s AI features in Search and the Gemini apps can read your email and photos to give more personal answers. The new wording means that, in Search, turning this on can also shape your ads. It is a choice, but the link to ads is easy to miss.

- Safety & Security
Critical PHP flaws, found with AI help, take sites offline
PHP runs a large share of websites, and it had two serious flaws.
Why it matters: PHP’s own team saw the first signs of one flaw in 2024 but could not agree on a fix. Reports made with AI help in August showed how dangerous it was. Experts quoted by Reuters fear that AI tools will now also help attackers move fast, because the fix is public.

Salesforce agrees to buy marketing firm Braze for $5.66B
Salesforce wants to buy Braze, which sends brands’ messages to their customers.
Why it matters: Big software companies are buying tools that let AI agents act on customer data in real time. Salesforce’s own marketing business has been shrinking, analysts told Investor’s Business Daily, so it is paying a large premium for a rival that was winning customers.

Amazon open-sources TorchNeuron to run PyTorch on Trainium
Amazon released TorchNeuron, a free and open-source tool, as a public beta on October 20.
Why it matters: Most AI code is written for PyTorch, and Nvidia’s software has long made its chips the easy default. If moving code to other chips gets simple, cloud customers get a real choice. How simple it is in practice is still Amazon’s claim.

doubleAI says its Maxwell model makes code run faster
doubleAI, an Israeli startup, launched Maxwell, a tool that speeds up programs while they run.
Why it matters: Computing power is the biggest cost of AI. A tool that makes the same chips do more work could cut bills without new hardware. But no outside group has tested Maxwell yet, so the speed-ups remain claims.
