"Let the unit die and just create new ones every few years" is a brilliant solution to many issues in complex systems. Practically all software created by humans behaves the same way - want a new version of your browser or a new major version of your OS kernel or whatever else - you have to restart them.

"The creatures outside looked from DNA to k8s YAML, and from k8s YAML to DNA, and from DNA to k8s YAML again; but already it was impossible to say which was which."

Death isn’t a solution to maintenance issues, there are some organisms including animals that live many hundreds of years and possibly indefinitely. The reason seems to be to increase the rate of iterations, to keep up the pace of adaptation and evolution.

its a pretty amazing hack though

the human body can scale from 1 cell to several trillion without going down for maintenance even once all while differentiating to different functions

it can take a high level of damage and heal without needing a shutdown as well, most software crashes completely at the first exception

cells give you that highly scalable and fault tolerant system that we all want

Poor comparison - DNA is compiled assembly language code. It is meant to be spaghetti to save space and reuse proteins for multiple functions. In that regard it’s the most efficient compiler in the universe.

And it’s still more adaptable/robust/intelligent than almost any system we’ve built so far.

Hello IT. Have you tried turning it off and turning it back on again?
