Google's AI org had its biggest personnel shake-up in years: Demis Hassabis moved up to chair of DeepMind and chief scientist of Alphabet, while 27-year veteran Jeff Dean departed, a shift The New Stack frames alongside Meta's own coding-agent stumbles and expectations that today's OpenAI Codex will look 'primitive' by fall. On the infrastructure side, SpaceX said it will standardize its data centers exclusively on Nvidia hardware, Samsung laid out its HBM roadmap, and Texas paused new datacenter approvals - signs the AI buildout is bumping into real-world constraints. Security teams had a rough day: a resurgent Shai-Hulud npm worm hit over 1,280 packages including Keyv, a separate self-propagating supply-chain attack compromised 400+ npm packages to steal cloud credentials, and a critical pre-auth macOS bug gives remote root in under a minute. Meanwhile plenty of solid engineering shipped quietly: Netflix detailed a petabyte-scale time-series storage abstraction, Microsoft finished moving 1,600 repos and 3,100 developers off Azure DevOps onto GitHub, and Google Cloud's API Gateway added LLM model routing in public preview.
