Linus Torvalds criticized a proposed helper function for being ambiguous and adding cognitive load instead of clarity. The article discusses how clearer naming conventions can improve code readability and reduce confusion. It suggests that while abstractions can be beneficial, they must be explicit to be effective.

High cognitive load in software development can hinder understanding and efficiency. To mitigate this, developers should focus on reducing extraneous cognitive load by simplifying code structures, preferring deep modules with simple interfaces over numerous shallow ones, and adjusting designs to minimize confusion and maximize clarity. Emphasizing the importance of cognitive load can lead to better software practices and more maintainable codebases.
