We Aren't Designing Software For Robots
For some reason, many programmers seem to struggle with the concept of people being different. They get hung up on this naïve concept of right or wrong, as if life is some kind of mathematical equation that has a closed form solution. Let me say right now that any solution to life is going to be one heck of a chaotic nonlinear PDE, which won't have any closed form solution at all, and certainly not one using elementary functions. When you are developing software, you must keep in mind the range of customers who will be using your product, whether they are office workers or fellow programmers.
Maybe someone is using your product to try and finish a presentation in time to go home and catch a nap before they get up to work their second job so they can support a wife and a screaming baby. Someone else might use your product to track their progress as they try to revolutionize search from their bedroom instead of study for their finals next week. Someone else might be an elderly man trying to figure out how his vacation is going to go.
We are all different. We arise from all walks of life and are bound together in a great journey on this blue ball hurtling through space. It is not cowardice when two people try to put aside their differences and work together, it is strength. It requires enormous courage to admit that there are no simple answers in life. There are no answers in the back of the textbook. There are many different answers, all different in subtle ways, all suitable for slightly different circumstances, all both right and wrong in their own, strange, quirky ways.
Some programmers seem distressingly incapable of compassion or empathy. Many claim to live through the cold hard logic of data, without apparently realizing that data itself is inherently meaningless. It is only given meaning through a human's interpretation, and a human can interpret data to mean whatever they want. They seem to think they can solve problems by reducing everyone into neat little collections of numbers that can be easily analyzed. It's certainly a lot less frustrating to work with real numbers instead of real people, but inevitably, a programmer must come to terms with the fact that life is about human beings, not numbers on a screen.
The cold hard logic of our code is good for speaking to computers—it is not good for speaking to other human beings.
