Summary

The discussion, sparked by Dan Luu's article on performance optimization, centers on the claim that modern software is unnecessarily slow due to neglect of optimization. Commenters largely agree that hardware improvements have enabled sloppy coding, but debate whether the trade-offs for developer velocity and feature complexity justify the performance costs. A consensus emerges that while there's no technical excuse for bloat, organizational incentives and tooling gaps often prevent optimization.
