New book Proof Over Promise argues credentials are depreciating signals in the AI era

Alec_Coughlin · x · 2026-11-14

William Zhu's book Proof Over Promise: How to Build an Undeniable Career in the Age of AI argues that careers are advanced by gatekeepers who rely on signals — and the classic signal of "promising credentials" (Ivy degrees, big tech, MBB, Goldman) is depreciating. US master's degrees have nearly quadrupled since 1971, so identical credentials separate no one, while AI now performs knowledge work that once required years of specialized training, shrinking the expertise premium those degrees certify.

The book's answer: proof over promise — what you actually build beats what your resume predicts. It targets readers deciding on MBAs/PhDs, promotions, or how to use AI to stay ahead. Full audiobook runs about 3.5 hours, with Substack, PDF draft, and audio versions available.
