Worse Is Better, for Better or for Worse
summary
Revisits Richard Gabriel’s “worse is better” claim that simpler, smaller implementations win by trading completeness for correctness and speed, arguing for minimal invention, easy deletion and ecosystem interoperability. Cited examples: the original wiki implemented in 150 lines of Perl, Unix v6 at about 10,000 lines, and a study showing three quarters of production failures are reproducible by unit tests. Emphasizes fast, small, testable code, parsimonious abstractions, and scope reduction as the practical path to reliable, changeable systems.
