What an arrogant posting (presumably by a web developer). Go write some mathematical software or anything serious at all and you'll find soon enough that typing is not even remotely the bottleneck.
This "typing is not the bottleneck" is such a cliché - I nearly wrote about it in the article. It presupposes that programming is some kind of pipes-and-filters activity where we're thinking and then typing and then compiling. I don't know about you, but when I'm programming I work in different states. Sometimes it actually is about getting the code into the computer as fast as possible. Not all the time, but sometimes.
