The key point here is our programmers are Googlers, they’re not researchers. They’re typically fairly young, fresh out of school, probably learned Java, maybe learned C or C++, probably learned Python. They’re not capable of understanding a brilliant language. But we want to use them to build good software. So, the language that we give them has to be easy for them to understand and easy to adopt.

Rob Pike

If a company chooses to write its software in a comparatively esoteric language, they'll be able to hire better programmers, because they'll attract only those who cared enough to learn it.

Paul Graham, The Python Paradox
