> What machines do with it is of lower priority. Why? Because a programmer's time is far more expensive than any infrastructure cost. This assumes that code runs on corporate infrastructure. What if it runs on an end user device? As a user I certainly care about my phone's battery life. And we aren't even talking about environmental concerns. Finally, there are quite a few applications where speed actually matters. > Comments is a self-admission you failed to write readable code, and you can fix your failure by refactoring code into self-descriptive member functions. Self-explaining code is a noble goal, but in practice you will always have at least some code that needs additional comments, except for the most trivial applications. The world is not binary.
