Isaac Askew, Dustin Rea, and Jeffrey Sherman discuss the outdated programming technique of bit masking, exploring its historical context, current relevance, and the cognitive load it imposes on developers. They emphasize that while bit masking may still have niche applications in high-frequency trading, the general trend in software development has shifted towards prioritizing engineering time and maintainability over micro-optimizations. The discussion highlights the importance of understanding when efficiency is truly necessary and when it can be sacrificed for better clarity and ease of development.
