Most people use age to decide if a memory is useful.
They assume new memories are fresh and old memories are bad. This is a mistake. Time is a poor way to measure truth.
Consider these two scenarios:
- You write a note about a code module today. You change that module tomorrow. Your note is one day old but it is now wrong. It describes something that no longer exists.
- You write a note about a security process a year ago. That process never changes. Your note is old but it is still perfectly accurate.
Age does not matter. What matters is lineage.
A memory stays fresh only if the thing it describes stays the same. If you change your direction or abandon a project, every lesson from that project becomes stale instantly. It does not matter if those lessons are five minutes old. The connection to your current path is dead.
Stale memories are dangerous.
A missing memory makes you cautious. A wrong memory makes you confident in the wrong direction. An agent or a person follows a stale instruction and breaks a system because they trusted something that used to be true.
Why do we use age then? Because age is cheap.
Every note has a timestamp. Tracking lineage is hard. To track lineage, you must map every memory to the moving parts of your system. Most people do not build that map. They use the cheap proxy of time instead.
Stop asking how old a memory is. Start asking if the world it describes still exists.
How do you handle this? Do you trust recency and accept the errors, or do you link memories to the things they describe?
