⚡ Block Cuts 40% of Workforce — Jack Dorsey Cites AI Productivity
ai-workforce-economics
Jack Dorsey cut 4,000 jobs — nearly half of Block — attributing the decision to AI productivity gains, while former employees and critics argue the actual work cannot be automated. The AI-washing question now has teeth: when executives frame mass layoffs as AI-driven efficiency, the burden of proof matters — and here, it's being contested publicly by the people who did the work.
🔧 NVIDIA Vera CPU: First Processor Purpose-Built for Agentic AI

NVIDIA launched the Vera CPU at GTC 2026 — 88 Olympus cores, 1.8 TB/s NVLink coherency with GPU, 2x energy efficiency versus traditional rack CPUs, supporting 22,500+ concurrent RL environments per rack — designed from the ground up for agentic workloads, not repurposed for them. Every prior "AI CPU" was legacy silicon wearing a different badge; this is the first one where agentic reinforcement learning was the primary design constraint.
🏭 NVIDIA Vera Rubin: 7-Chip Platform for AI Factory Scale

Now in full production, Vera Rubin achieves 10x inference throughput per watt and one-tenth cost-per-token versus prior generations, with NVL72 training MoE models at one-fourth the GPU count of Blackwell. The numbers are the point — use cases that were cost-prohibitive last quarter are not this quarter, and that inflection is arriving faster than most deployment roadmaps anticipated.
