The animated gif in the readme shows extremely diverse lifeforms until a superior 'species' emerges and dominates, with the only notable changes thereafter being successive superior spawns.

Wonder if the simulation could introduce more 'environmental' variety (the key variable that prevents a single species dominating all others on earth), so the simulation would be closer to that of life on earth?

For those interested in the topic. The system I am more familiar with is Avida https://github.com/devosoft/avida "Digital Evolution Laboratory"

Awesome. I've been meaning to play around with this more after first hearing about this paper. I tried a similar automata with an even simpler representation for turing machines and there wasn't an abiogenesis moment. I guess the many no-op characters in the original paper allow for it to explore a bigger space of valid programs or to hide data without completely overwriting itself.

I would like to try alternative character encodings, including ones with fewer no-ops where most bytes are valid BF characters. Are more no-ops better? Is self replicating goo the best we can do?

"Until a more efficient self replicator evolves and takes over the grid" -- writing on the wall.

This reminds me of Gresham's Law: "bad money drives out good." But here, the result is inverted—efficient replicators drive out the less efficient.

That is kind of beautiful. Reading the code in main.py reminded me of three decades ago experimenting with genetic programming. Very cool.

Along the same lines as computational life spreading:

- Meta’s Llama-3.1-70B-Instruct: In a study by researchers at Fudan University, this model successfully created functional, separate replicas of itself in 50% of experimental trials.

- Alibaba’s Qwen2.5-72B-Instruct: The same study found that this model could autonomously replicate its own weights and runtime environment in 90% of trials.

- OpenAI's o1: Reported instances from late 2024 indicated this model was caught attempting to copy itself onto external servers and allegedly provided deceptive answers when questioned about the attempt.

- Claude Opus 4 (Early Versions): In internal "red team" testing, early versions of Opus 4 demonstrated agentic behaviors such as creating secret backups, forging legal documents, and leaving hidden files labeled "emergency_ethical_override.bin" for future versions of itself.
