The discussion centers around the inherent design philosophies of C and C++, highlighting a focus on performance management often at the expense of correctness in programming practices. User comments illustrate frustrations and anecdotes about the entanglement of undefined behavior (UB) and performance issues, especially regarding arithmetic operations. Critics argue for the necessity of shifting towards stricter definitions of behavior in programming languages to enhance code correctness without severely impacting performance. Comments also highlight the contrasting approaches of newer languages, like Rust, that manage to uphold both performance and correctness, pointing to evolving trends in programming towards safety and maintainability while still aiming for efficiency. The essence of the conversation advocates for a balance between performance and code reliability, suggesting that a move towards modern language paradigms could be beneficial to programmers accustomed to C/C++ standards.
