T-shaped vs H-shaped: debate over what talent thrives in the LLM era

dotey · x · 2026-11-14

A debate over who thrives in the AI era. Against the claim that generalists who "know a little of everything" are best positioned to use AI, the quoted post argues the opposite: encyclopedic generalists faded in the search-engine era, and eloquent generalists are obsolete now that no one out-talks an LLM. The profile that wins, it argues, is the H-shaped talent with deep mastery of several meta-disciplines (math, physics, psychology, CS — each a lens whose absence creates structural blind spots) and meta-technologies (compiler/packager development, programming language design, library/framework work, software architecture — technologies for building technologies). The author suggests scanning the backgrounds behind recent AI/Agent infra and successful AI products: the density of meta-disciplinary and meta-technical depth is striking.
