Man is driven to create; I know I really love to create things. And while I'm not good at painting, drawing, or music, I can write software.

Language designers want to design the perfect language. They want to be able to say, 'My language is perfect. It can do everything.' But it's just plain impossible to design a perfect language, because there are two ways to look at a language. One way is by looking at what can be done with that language. The other is by looking at how we feel using that language-how we feel while programming.

I didn't work hard to make Ruby perfect for everyone, because you feel differently from me. No language can be perfect for everyone. I tried to make Ruby perfect for me, but maybe it's not perfect for you. The perfect language for Guido van Rossum is probably Python.

Often people, especially computer engineers, focus on the machines. But in fact we need to focus on humans, on how humans care about doing programming or operating the application of the machines.

I hope to see Ruby help every programmer in the world to be productive, and to enjoy programming, and to be happy. That is the primary purpose of Ruby language.

Smart people underestimate the ordinarity of ordinary people.

Most programs are not write-once. They are reworked and rewritten again and again in their lived. Bugs must be debugged. Changing requirements and the need for increased functionality mean the program itself may be modified on an ongoing basis. During this process, human beings must be able to read and understand the original code. It is therefore more important by far for humans to be able to understand the program than it is for the computer.
