Ben Goertzel Proposes the “Omega Ray,” a Model of a Self-Modifying Mind That Preserves Its Direction and Connection to Earlier Versions
On August 15, Ben Goertzel published the essay “Time’s Arrow, Part 2”. He connects subjective time to the recording of new, meaningful distinctions and proposes giving future versions of a mind access to the history of its changes.
When a mind rewrites its models, expands its memory, and learns new forms of reasoning, its future version stores and processes experience differently. Continuity between versions depends on whether the later version can translate earlier ways of representing experience into its new representations.
The analysis of digital personal continuity distinguished working memory, which holds the current thought, from episodic memory, which connects a person to the past. Goertzel poses a related technical problem for a self-modifying mind: after changing its own ways of thinking, a later version needs an archive that it can still read.
In Goertzel’s model, subjective time grows as meaningful distinctions are recorded. These distinctions change the world model and later help the system choose an action. When the system learns to handle unfamiliar situations, it must preserve the distinctions on which its choices depend.
This reasoning leads Goertzel to the “Omega Ray.” A mind retains a common direction, including its values, its capacity for self-correction, and its ability to coordinate its parts, while its history of experience continues to grow. In this model, stability lies in that direction, while the internal state changes as the history grows.
Rapid self-modification makes this continuity more demanding. Goertzel states the requirement as follows:
“The faster the stream of distinctions, the smaller the average self-translation error must become.”
As an engineering step, he proposes dividing memory into two parts: rewritable working memory and an append-only log that records how the system reached its conclusions. The log retains both corrections and deletions. A later version can compare its transformations with the structure of earlier representations.
Goertzel thus gives the philosophical question of personal continuity an engineering form: a future version of a mind must be able to read its own history and verify its connection to earlier representations.
