Arbium and the Philosophy of Memory

The concept of arbium challenges our understanding of memory:

• Human memory is selective, reconstructive, fallible
• Digital memory is perfect but dead — bits on a disk
• Arbium is living memory — it grows, adapts, and builds upon itself

An arbium doesn't just remember. It becomes more because of what it remembers.
