I Built an AI Exposure Map for 280 Nigerian Jobs

After Karpathy's US job exposure map went viral last week, I noticed nobody had built anything like it for Nigeria or any African country. So I built it in a weekend. What it does aiexposure.com.ng scores 280 Nigerian occupations from 0-10 on AI automation exposure. Each job gets a score and a plain-English rationale explaining why. The treemap visualization shows every job — area represents employment size, color represents AI exposure (navy = safe, coral = high risk). The surprising finding Nigeria's workforce averages 3.6/10 on AI exposure. The US averages 5.3/10 . Why the gap? Nigeria's economy runs on physical presence, cash, and interpersonal trust: Okada rider: 1/10 — AI can't navigate Lagos traffic POS agent: 3/10 — cash-based trust networks aren't digitizable Suya seller: 0/10 — no algorithm can read that fire Software developer: 9/10 — yes, us too 53% of Nigerian jobs score 0-3 (low risk). The informal sector that people often overlook is mathematically the most AI-proof work
