>is that the systems are so dang tiny and crowded, with every molecule running into every other molecule every second or so, Per my two earlier comments [1], I would phrase it as an issue of biological systems optimizing soley for fitness, while (human-designed) computers are also heavily optimized for intelligibility, modularity, and ease of reasoning about. This makes it much easier to isolate and experiment with the subsystems and gain an understand, in contrast to biological systems, which will constantly bleed state across the entire system.
