AI Impact on Knowledge Work

How AI is disrupting knowledge work across law, finance, medicine, and engineering


AI is rapidly moving from "helpful tool" to a system that can independently complete complex knowledge work across software engineering, law, finance, medicine, and other fields. The pace of improvement — doubling the length of tasks AI can handle autonomously roughly every 4–7 months — suggests that most screen-based knowledge work faces significant disruption within 1–5 years, not decades.

The pace of improvement

METR, an organization that benchmarks AI capabilities, tracks the duration of real-world expert tasks that AI can complete end-to-end without human help:

The doubling time is ~7 months, possibly accelerating to ~4 months. Extrapolating: AI working independently for days within a year, weeks within two, month-long projects within three.

AI building AI

A critical feedback loop has emerged: AI is now being used to build the next generation of AI. OpenAI disclosed that GPT-5.3 Codex "was instrumental in creating itself" — used to debug its own training, manage deployment, and diagnose evaluations. Anthropic's CEO says AI writes "much of the code" at the company and that we may be "only 1–2 years away" from current AI autonomously building the next generation.

AI adoption is spreading faster than previous technology waves

Impact by field

The perception gap

A dangerous gap exists between public perception and current capability. Most people either tried early (2023–2024) models and dismissed AI, or use free-tier tools that lag paid versions by over a year. The people actually using frontier models daily for real work see a fundamentally different picture.

Emerging AI capabilities

Recent models display what practitioners describe as "judgment" and "taste" — an intuitive sense of what the right call is, not just technically correct output. The rule of thumb: if a model shows even a hint of a capability today, the next generation will be genuinely good at it.
