Expertise Still Beats AI

_{IN ONE SENTENCE}

Experts who use AI get a 10x multiplier; generalists who delegate everything to AI get an average result.

_{THE OBSERVATION}

There is a dominant narrative in the AI world: technology will democratize skills and make expertise obsolete. Ethan Mollick brings a crucial nuance grounded in research. Yes, AI narrows the gap between juniors and seniors for standard tasks. But for people in the top 2% of their field, AI becomes an unmatched force multiplier; up to 10 or 100 times their usual performance.

The BCG study confirms this counter-intuitively: seniors use AI better than juniors. Not because they are more technical, but because they know what to ask and how to evaluate the quality of responses.

The democratization paradox

The BCG study measured what Mollick calls retainment: how much of AI's work consultants keep as-is in their final deliverable. Result: for 80% of consulting tasks, the best strategy was to submit the AI's response without modifying it. As soon as a junior added their own ideas, quality dropped. In other words, juniors are not augmented by AI: they are replaced by it as intermediaries.

Expert + AI = the real competitive advantage

Mollick uses the example of the entrepreneur: someone who is at the 99.9th percentile in one domain but mediocre in all others. AI can bring this person to 80% competence in their weaknesses: management, pitching, business planning: while multiplying their core strength by 100. That's where real value is created.

Three profiles that win

According to Mollick, three types of profiles extract the most value from AI: deep experts in a specific domain, systemic generalists who think in terms of systems and connections, and people with excellent taste who know how to select and curate from the abundance generated by AI.

_{WHAT THIS CHANGES FOR YOU}

• Invest in developing deep expertise: AI amplifies the difference between experts and generalists
• Don't rely on AI to turn your juniors into seniors; it turns them into efficient intermediaries
• Value taste and curation as key skills in a world of AI-generated abundance
• Recruit for expertise and systemic thinking, not for prompting ability
