Nirvana fallacy (perfect solution fallacy)

Biological Parallel

DNA replication achieves 99.9999% accuracy, yet errors still occur—about one per billion base pairs. Rather than rejecting replication for imperfection, organisms layer on repair mechanisms: proofreading, mismatch correction, excision repair. Evolution doesn't wait for perfect solutions; it implements good-enough mechanisms and iterates. The 70% solution that ships beats the 100% solution in development. Biological systems that demanded perfection before acting went extinct waiting for conditions that never arrived. Adaptive refinement requires accepting initial imperfection.
