The Illusion of the Clean Slate

Short summary

A successful system rewrite isn't a clean slate—it's a translation of organizational memory. The old system's complexity came from genuine constraints (regulatory, customer, performance) and lessons learned the hard way. The best rewrites acknowledge this inheritance, preserve what works, and consciously improve what can be changed.

• •Rewrites can't escape organizational memory, legacy workflows, or the real constraints that shaped the original system
• •Fresh implementations rediscover the same edge cases as new bugs because the reasoning behind design decisions gets lost
• •Successful rewrites treat previous systems as translations to preserve, not mistakes to erase
