The Shape of Memory: Functors, Monads, and the AI Mind | by Satyam Mishra | Apr, 2025


In category theory, a monad is a special structure:

Together with two natural transformations:

  • Unit: η : id_C→T
  • Multiplication: μ : T^2 → T

In programming, monads model effects: computations with context.

In memory, monads model self-reflection — thoughts about thoughts.

  • Imagine an AI that retrieves a memory, then re-queries it with additional context, then loops again.

This recursive loop is monadic thinking.
Memory becomes layered with meaning, not just stored.

Satyam’s Analogy:
You remember “a red apple.” Then you remember why it mattered — “gift from mom.” Then you reflect again — “I miss her.”
Each layer is a monadic wrap.
