For decades, the equity value in corporations has rested on their ability to build and defend “moats” — structural barriers that protect profits from competition. These moats have come in many forms: scale, brand, distribution, information asymmetry, and switching costs. They created stability for incumbents and concentrated power in large, bureaucratic organizations.
Generative AI is systematically weakening these barriers. The result is not only business model erosion at the firm level but also a potential reshaping of entire economies.

From Scale to Individual Leverage
Scale once justified headcount. Hundreds of analysts, marketers, or designers were needed to sustain output. Now individuals and small teams can harness AI to achieve capacity that rivals entire departments.
- Example: A two-person startup can now produce marketing campaigns, financial models, and investor presentations that previously required dozens of staff. Indie game developers using AI for art and dialogue design can compete with mid-tier studios that once relied on large teams.
Organisational scale still matters in capital-intensive industries (like manufacturing or energy), but in knowledge work it is becoming far less decisive.
From Information Asymmetry to Commoditised Knowledge
Consulting firms, data vendors, and publishers thrived by owning proprietary insights. AI undermines this advantage by synthesizing public data at scale, surfacing answers once locked inside databases or hidden behind paywalls.
- Example: Legal AI tools such as Harvey or Casetext can draft briefs and conduct case law research at a fraction of the cost of junior associates, eroding law firms’ advantage in information-heavy tasks. Market research once requiring paid reports from Gartner or McKinsey can increasingly be replicated with AI-driven synthesis.
Knowledge is becoming less about what you own, and more about how you contextualize and apply it.
From Network Effects to Layer Inversion
Platforms like Amazon, YouTube, and Airbnb have long benefited from network effects. The more users and suppliers they attracted, the stronger their position became. Continue reading
