Hmm, I have a few points to add regarding the self-replication cycle. There's actually existing research on Von Neumann probes and self-replicating factories that you might find relevant (e.g., "Replicating systems concepts: Self-replicating lunar factory and demonstration," and also this paper: https://arxiv.org/abs/2110.15198).
(My native language is not English, so this comment was translated by Gemini 2.5 pro. Please forgive me if it sounds a bit like an LLM.)
Based on this, I'd like to offer a few supplements to your article:
1. The doubling time ...
Regarding the first point,
I apologize for the error made by the LLM during translation. The original phrase I provided was "the difference is not too significant" but it seems some words were omitted. However, I admit my example was weak and not suitable. First, birds have higher body temperatures, allowing for faster heat dissipation (so the hummingbird, compared to the elephant, is actually closer to the ^2/3 scaling law and deviates more from Kleiber's law). Second, evolution has favored lower resting metabolic rates to conserve energy, whereas our goal... (read more)
