AI news for June 23, 2026

Oracle states in a regulatory filing that it cut 21,000 employees over the past 12 months and attributes workforce reductions in part to the adoption of AI technologies.

• 21,000 job cuts over 12 months, a 13% headcount decline
• Company says AI adoption and deployment have resulted and may continue to result in workforce reductions
• Fits a wider pattern: May saw record tech layoffs with AI frequently cited as the reason

A major vendor explicitly linking layoffs to AI adoption indicates automation and AI-driven efficiency are having concrete workforce and operating-model consequences that businesses and advisers must factor into HR and investment decisions.

For you Inventory repetitive tasks in your firm and plan targeted upskilling or role redesign now to avoid disruptive cuts later.

OpenAI launches Patch the Planet in partnership with security firm Trail of Bits to help open‑source maintainers find, triage and fix security issues.

• Trail of Bits engineers will work directly with maintainers to review potential code issues
• OpenAI security tools, including Codex Security, will assist the process
• Program aims to filter findings before they reach maintainers, develop patches and tests, and create reusable workflows

Open‑source projects often lack resources to handle growing volumes of reports; coordinated help can reduce supply‑chain risk for commercial software. For SMEs this means a lower chance that widely used libraries introduce critical vulnerabilities into their stacks.

For you Identify which open‑source libraries are critical in your systems and watch whether they get covered by Patch the Planet; schedule regular security reviews for critical dependencies.

Nvidia says its Rubin data‑center reference design, using fully liquid‑cooled servers and higher operating temperatures, cuts water use to 'near zero.'

• Design switches to 100% liquid cooling; heat is captured at the chip and carried through high‑temperature liquid loops.
• Servers are run hotter — up to 45 °C (113 °F) — to allow outdoor dry coolers to reject heat efficiently.
• Nvidia cites reducing water use from roughly 2.6 million gallons per megawatt per year for conventional cooling‑tower systems to near zero, per sustainability head Josh Parker.

Liquid cooling can materially lower water use and improve thermal efficiency for AI data centers, but it doesn’t remove construction‑phase impacts or power‑generation needs and may raise build costs.

For you When planning or procuring compute, ask providers for cooling approach, water‑use metrics and cost comparisons; consider liquid cooling for long‑term large‑scale deployments.
