Does Typing Speed Really Matter For Programmers?

theodp writes "I can't take slow typists seriously as programmers,' wrote Coding Horror's Jeff Atwood last fall. 'When was the last time you saw a hunt-and-peck pianist?' Atwood's rant prompted John Cook to investigate just how important it is to be able to type quickly. 'Learning to type well is a good investment for those who are physically able to do so,' concludes Cook, 'but it's not that important. Once you reach moderate proficiency, improving your speed will not improve your productivity much. If a novelist writing 1000 words per day were able to type infinitely fast, he or she could save maybe an hour per day.' At 150 WPM, notes Cook, the world's fastest typist was still only 10x faster than Stephen Hawking."

How Absurd

When was the last time you ran a program where the WPM of the developer affected the quality of the code? Because the frequency of and careful regularity and emotion seriously affects piano performances whereas the symbols per minute inputted by a developer is independent of the speed, quality or maintainability of software. Sure, you might put forth that they can produce much more code or much more comments but let's face it: I'll take quality over quantity in regards to code any day of the week.

A short simple anecdote was my Greek professor in college. Taught me pattern recognition and I went to his office hours where he was pecking away at the keyboard having just been forced onto English QWERTY. The old man still wrote some pretty badass pattern recognition algorithms in Matlab for the course. Might have taken him all week to peck them out while looking at some recently published papers but the stuff was pretty efficient and easy to read for Matlab. I took him pretty seriously.

At my high school, in order to take advanced placement computer science courses, you had to pass some WPM typing course. Rarely have I felt a course to be such a complete waste of time and genuinely a turnoff to people looking to study programming.

The problem is that slow typists try to avoid doing much typing. This means that they avoid things like detailed comments and meaningful symbol names. To a quick typist, there's little extra cost in giving something a long name - they're spending more time thinking than typing anyway - and there's a huge benefit in terms of readability. A slow typist will be bottlenecked by typing speed, so will give things shorter names to improve throughput at the expense of readability. Someone who types quickly thinks very little of writing a few lines of documentation at the start of each function and of providing comments with full sentences explaining why various approaches were chosen. Someone who types slowly regards this as a chore, and usually skips it.

Yes, and no...

Of course it matters. Sometimes. Your 'rate of creation' is simply the min(rate_of_typing, rate_of_thought). If you can type faster than you are currently thinking/creating/"solutionizing" then no, it doesn't matter, and there are a lot of times during code creation where this is the case; you need time to noodle, try things out, think about a solution, need some time. But, there are times where you know EXACTLY what you want the code to do/be/look like, and those times your typing speed can be the bottleneck, and there are a lot of times during code creation where THIS is the case too.

The answer is "No"

Any reasonably intelligent person should be able to find the flaws in Atwood's analogies and synthesize several decent counter-arguments by themselves. The notion is ridiculous on its face and if the quality of this guy's analogies is any indication of his mental acuity then I'm surprised anyone reads his blog at all. I'm not sure why such a laughably flawed statement should prompt anything but derision, but Slashdot being what it is today, I suppose it is the right place for such a discussion to take place.
