In software systems it is often the early bird that makes the worm.

Insight: There's a funny reversal buried in this programmer's joke. Usually we hear "the early bird gets the worm"—success goes to those who move fast. But Perlis flips it: in software, being first often means you're the one who creates the mess that everyone else has to untangle later. You write the foundational code, make the initial design choices, and inadvertently set traps for everyone downstream. This applies way beyond programming. Think of the person who establishes a process at work, the friend who sets the tone in a group chat, or the first person to take on a new responsibility. They're not necessarily winning—they're often creating problems they don't fully see. Early movers have incomplete information and no way to learn from what came before. They become the worm, in a sense, stuck in the system they created. The real insight is that being first isn't automatically an advantage. Sometimes it means inheriting your own mistakes, and later arrivals get to benefit from your hard-won lessons while sidestepping your early errors. Maybe the second mouse does get the cheese after all.
