> IMHO Unicorns are built with the assumption that almost every developer is replaceable. At that scale the critical knowledge is not with the developers. Critical knowledge is with the developers unless: 1. The system is stable and feature-complete. 2. You've employed about 10 FTEs documenting every aspect of the thing. If those two criteria aren't met, they system becomes tech debt, a larger risk, and will likely decay until replaced.
