Today I engaged in yet another discussion about the need of touchtyping for programmers with few of my collegues. My position on this issue is ver well known - I think that touchtyping is a requirement for a good programmer. I accept, of course, that there are few good programmers out there who can’t touchtype, but they are very few and they are only an exception that supports the rule.
While in said discussion, I was trying to come up with a good analogy from a non-IT area for a programmer who can’t touchtype. I know of two ways to come up with a good analogy.
