Relationships are coevolutionary loops

• Treat relationships like software: keep a "bug log" of weekly friction points, debug systematically, and iterate on your routines until life runs smoothly
• Iteration speed matters more than compatibility—the faster you learn about each other and act on that knowledge, the further you can evolve together
• High-bandwidth communication (3-4 hours of daily conversation early on) builds reserves of shared language and trust that buffer against future friction
• Constraints force creativity: aligning two divergent life paths requires more ingenuity than going solo, leading to surprising outcomes neither person would have chosen alone
• Relationships need responsiveness like old houses that adapt over decades—static, preplanned visions alienate; fluid systems that change with you create home

The author uses Darwin's orchid-moth coevolution as a lens for understanding how relationships shape identity. When you meet someone truly comfortable in their strangeness, there's usually someone who enabled that evolution—a parent, friend, or partner who gave them space to unfold. The essay chronicles how the author and his partner Johanna built their first home together, not just physically but as an "emotional space in which the coevolutionary loop plays out."

The core practice: treating their relationship like software development. They kept a weekly "bug log" on a blackboard listing everything that went wrong, then systematically debugged their routines and principles. Want to wake at 5am but keep sleeping in? Identify the bottleneck (not feeling sleepy at night), experiment with solutions (cutting coffee), iterate until it clicks. This explicit feedback loop—writing down friction, discussing goals and assumptions, rapid experimentation—is what allowed them to evolve together at high speed. The author argues iteration speed is more important than initial compatibility: the best scientists aren't the smartest, they're the ones who tweak theories fastest in contact with reality. Same with relationships.

The practical infrastructure: talking 3-4 hours daily in their early years, building massive reserves of shared language and context. Living without internet for a year. Moving to a small town where no friends visited, creating wide-open time for reading, learning, and conversation. The constraints of aligning two divergent life paths (he wanted literary New York, she wanted cheap rural autonomy) forced creativity, like how metrical rules in poetry "forbid automatic responses, force us to have second thoughts, free from the fetters of Self." The result: lives that turned out "much weirder than planned," shaped by a coevolutionary loop neither could have designed alone.
