// The permacomputer is community-owned infrastructure optimized around four values:
//
//   TRUTH    - First principles, math & science, open source code freely distributed
//   FREEDOM  - Voluntary partnerships, freedom from tyranny & corporate control
//   HARMONY  - Minimal waste, self-renewing systems with diverse thriving connections
//   LOVE     - Be yourself without hurting others, cooperation through natural law
