Barriers to entry have collapsed — unlimited compute access, abundant capital, and talent mobility mean incumbents face exponentially higher disruption risk; hardest investor task is assessing durability.

Market over-rotates to chips/semiconductors/energy, leaving durable platforms (Amazon, Meta, Microsoft) at historically low multiples — analogous to 2000 when Berkshire hit trough while internet stocks soared.

Insurance float + surplus invested in equities creates perpetual compounding; most insurers fail because talent goes to hedge funds — owner-operator alignment solves this. HHC repurposing real estate cash into insurance float targets 50-year trillion-dollar outcome.

Companies charging $30K/seat for niche software are vulnerable; platform players like Microsoft at $50/seat with AI integration have wider moats — must be AI-enabled or face obsolescence.

Late-stage private giants (SpaceX, xAI) should be underwritten as venture bets — assess founder quality, market uniqueness, competitive context, then deal terms; traditional DCF fails for monopoly-like trajectories.

Three permanent capital vehicles (Pershing Square Holdings, PSUS, Howard Hughes) with 2% fee, no redemption risk, and aligned incentives can compound for decades — structural edge over traditional hedge fund model.

Despite universal CEO focus on AI as top threat/opportunity, actual success stories are rare — Pershing Square's own legal/compliance use case is typical; forward-deployed engineers emerging to bridge promise-ROI gap.
