Steve Yegge: AI-built systems will eventually outgrow their own understanding—debt compounds superlinearly
teropa · x · 2026-09-03
Steve Yegge argues that any model, however smart, will eventually build systems it can no longer understand or maintain if left unchecked—Fable 5 outbuilt itself and flailed for a week; Fable 5.1 looks like a fix, 'for now.' Retweeter 0xblacklight lays out the logic: LLMs correctly seen as better than humans at working in bad codebases led people to wrongly conclude code quality no longer matters—but models generate bad, complex code far faster than they improve at handling it, and this debt compounds superlinearly on large teams. Keep an iron grip on system size or it will run away from you.
