Prompt Notes #5 - weekly AI digest
AI goes fast. Helping you (and myself) catch up.
Welcome to the 5th edition of Prompt Notes, your new favourite weekly AI digest.
This edition will cover the week from 2 March to 8 March.
What caught my attention
The Pentagon labelled Anthropic a supply chain risk while running Claude on classified systems. Anthropic is suing. A million new users a day are switching to Claude. ChatGPT downloads are dropping.
OpenAI is pulling a Yahoo - chasing government contracts and enterprise deals while quietly losing the thing that actually matters: being the AI people want to open. Defaults shift. Faster than anyone admits. Claude is starting to feel like that shift.
TLDR
Pentagon vs Anthropic - A company providing AI to classified government systems gets labeled a supply chain risk by the same government. Anthropic is suing. The precedent this sets for every AI startup near defense work is significant.
OpenAI/Oracle halt Stargate Texas expansion - Power supply delays stall the flagship data center while Nvidia pivots chip supply away from China. The infrastructure bottleneck is real and getting worse.
AI memory-chip shortage - AI demand is triggering a historic shortage expected to raise prices across phones, cars, and electronics. Not an AI story. A consumer economics story.
Caitlin Kalinowski resigns from OpenAI - Head of robotics walks over the Pentagon deal, citing mass surveillance and lethal autonomy concerns. Senior talent voting with their feet is a signal worth tracking.
AI agent benchmarks ignore 92% of the labor market - Study finds benchmarks obsess over coding tasks while the vast majority of jobs go unmeasured. The gap between what we’re optimizing for and what actually matters keeps widening.
