What happened
A venture investor argues that the hundreds of AI productivity tools launched in 2023–2024—including coding assistants, legal tools like Harvey, and note-taking apps like Granola—are largely destined to fail because they lack durable competitive advantages. The writer notes that AI applications collectively push an estimated $150–200BN in ARR, but the quality of that revenue is among the riskiest ever.
Why it matters
The article contends that while AI productivity tools deliver on their promises, they cannot survive as standalone businesses when the pace of innovation is unprecedented and AI models themselves face threats from open-source competitors and new entrants. Only tools that evolve into true autonomous systems of work—capable of completing months of human labor independently—will thrive; the rest will perish.
What to watch
The investor predicts the next 12 months will shift from efficiency gains toward innovation in AI for science, autonomous defense systems, and physical AI, potentially larger than all digital AI combined. The author's firm has begun leading funding rounds in excess of several hundreds of millions of dollars for autonomous work systems since the beginning of 2026, marking a move away from simple productivity tools.

The article is built on a distinction between productivity tools (which automate narrow tasks) and autonomous systems of work (which complete months of human labor independently over long horizons). The writer observed the 2023–2024 explosion of AI productivity tools—from coding to law to medicine—and concludes that most will fail not because they don't work, but because they lack economic moats in a landscape where innovation moves too fast. The author uses the AI coding vertical as evidence: it evolved from GitHub Copilot (a basic assistant) through Cursor and Claude Code into full autonomous systems like Blitzy and Factory, each generation rendering the previous one obsolete. The article implies this trajectory will repeat across all verticals—AI doctors and lawyers will eventually compete not as tools but as autonomous replacements for human work. The writer's own investment thesis supports this: the firm sat idle for over a year, refusing to deploy capital into productivity tools even as they drew vast funding, until the technology to build true autonomous systems arrived in early 2026. The framing shifts the investment mandate from efficiency and productivity increases (the pattern of 2023–2024) toward innovation in science, defense, and physical AI—domains where autonomous systems can create entirely new value rather than simply automating existing work.
