The Big Idea#

Predicting complex system outcomes—whether estimating the long-term equilibrium of AI compute markets or debugging the interplay of LLM agents in a terminal—rarely succeeds from a purely bottom-up, theoretical approach. Instead, engineers and strategists must rely on robust instrumentation, structured runtime observation, and top-down heuristics to understand evolving behaviors before they settle into a definitive state.

Ways to think about token pricing · Benedict Evans Evans argues that the current AI supply crunch obscures the long-term economic fate of foundation models, questioning whether they will achieve sustainable pricing power or devolve into low-margin commodity infrastructure. He dismisses bottom-up modeling—like estimating chip counts and datacenter capex—as a fool’s errand, akin to forecasting the 1998 broadband market. Instead, he proposes focusing on top-down structural questions regarding the durability of the frontier, market competition, and the necessity of software “wrappers” to capture value. The core insight is that unless a massive disruption occurs—such as state regulation or unforeseen network effects—current dynamics suggest models will become commoditized layers where value is captured further up the stack. This is an essential read for anyone trying to model the unit economics of AI features or allocate infrastructure spend over the next five years.
