Smart people underestimate the ordinarity of ordinary people.

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.

The orthogonal features, when combined, can explode into complexity.

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.

It is not the responsibility of the language to force good looking code, but the language should make good looking code possible.

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.

Plant a memory, plant a tree, do it today for tomorrow.
