Luu re-ran the widely-shared Alderson result (J at 70 tokens average vs Clojure's 109) and showed it was an artifact of trivial Rosetta Code problems. His replacements: implementing a full Zstd decoder from RFC specs with no tests, and the Pandoc task from ProgramBench scored against holdout tests, across ~24 languages using GPT-5.6 Sol at medium and ultra effort. Pre-registered predictions held. The dynamic-language advantage and the "weird language" advantage both vanish at real complexity, and a weak-to-moderate positive correlation emerges between language popularity and solution quality. Pick for ecosystem depth, not token thrift.
