! learning intelligence.
!
! 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
!
! This software contributes to that vision by enabling code execution across 42+
! programming languages through a unified interface, accessible to all. Code is
! seeds to sprout on any abandoned technology.
