AI's transformation of work
A running log
Sat Feb 28, 2026, 3:47 PM EST
Block CEO Jack Dorsey laid off over 4,000 employees in February 2026, nearly half the company, stating that AI tools paired with smaller teams have fundamentally changed what it means to build and run a company. Sequoia Capital had already declared in January that AGI has functionally arrived through coding agents that work autonomously for hours. The financial markets felt it too. Anthropic triggered five separate stock selloffs in four weeks, the iShares Software ETF fell 35% from its September peak, and Tailwind CSS cut 75% of its engineering team after AI-generated code collapsed documentation traffic and revenue nearly 80%.
The capability driving these changes is concrete. Stripe’s autonomous agents produce over 1,300 pull requests per week with no human-written code, Anthropic is 70% to 90% AI-generated company-wide, and an OpenAI team shipped a full product producing a million lines of code with initially just three engineers. Andrej Karpathy named December 2025 as the hard threshold when agents stopped failing and started completing hours-long tasks reliably. METR’s February 2026 benchmarks confirm it: autonomous task-completion time horizons continue growing exponentially.
The transformation is moving beyond software engineering. A two-person boutique law firm now handles workloads that previously required teams of associates, using Claude to produce tracked-changes redlines, research memos, and real-time contract analysis without opening Word. UChicago political economist Chris Blattman, who does not code, used Claude Code in early 2026 to cut grant proposal writing from 12 hours to 1 to 2. Google reported over 25% of new code AI-generated as of late 2024, Microsoft 20 to 30%, and Nvidia deployed Codex to all 30,000 engineers in 2026. The pattern is clear. What started in programming is reaching law, academia, and knowledge work broadly.
