Deterministic about where, probabilistic about what
Silicon · predictability ·
- Predictability and determinism are different axes.
- An architecture must be deterministic about where data moves, but the algorithm can be probabilistic about what the data means.
- Exact state needs tight margins, high energy and strong error correction.
- State that tolerates noise and drift can live in smaller, cheaper storage next to the compute, and correctness moves from every operation to the outcome.
