⚡ 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.
