Write-Only Code | Heavybit

Much as humans no longer shell into individual production servers, I believe we will develop similar practices around unread code. Over time, we will treat “humans had to read this to be comfortable” as a smell in our code generation pipeline, or as an explicit, expensive trade-off reserved for truly mission-critical subsystems. A natural outcome of this shift is a “code reading coverage” metric, tracked much like test coverage. What fraction of production code has actually been read by humans, partly as a safety signal, and partly as a metric teams deliberately and safely work to drive downward toward an asymptote.
