Vibe coding simultaneously hit three inflection points this week: the UK NCSC warned it introduces security risks requiring secure-by-default code generation standards; Workday's CEO stated 'no amount of vibe coding will produce an HR or ERP system'; and Pega shipped enterprise vibe coding in Blueprint with governance guardrails built in. The $4.7B market (38% CAGR) is bifurcating: horizontal SaaS tools (PM, CRM, forms) face genuine replacement risk, while vertical/regulated enterprise software is absorbing vibe coding as a feature rather than being disrupted by it. The pattern: every disruptive tool eventually gets tamed by enterprise requirements.
