Why Most Knowledge Work Is Already Replaceable by AI

Daniel Miessler, a cybersecurity veteran who worked at Apple, Robinhood, and HP, makes a systematic case that most corporate knowledge work isn't actually complex - it's chaotic, poorly documented, and inconsistently executed. He breaks capability into four layers: knowledge, understanding, intelligence, and creativity. AI already handles the first three well, and McKinsey data shows only 4% of work requires median-level human creativity. The Gallup numbers reinforce his point: 62% of workers do the minimum, 15% are actively disengaged, and 28% of US adults lack workplace reading proficiency. His "expertise ratchet" concept is the stickiest idea - once knowledge gets captured in documentation, skills files, or code, it never leaves the AI pool. Meta, Amazon, and PwC have all started citing AI efficiency in layoff justifications this month, and Miessler's framework explains exactly why that trend will accelerate rather than plateau.
