The work Jeff Dean seems to be doing is _excellent software engineering_. 'Software Engineering' here I would define as 'the application of computer science'.

The work Jeff Dean seems to be doing is _excellent software engineering_. 'Software Engineering' here I would define as 'the application of computer science'. Which is not a far fetched definition, although many dismiss it when the topic is raised. He does that very well, applying computer science in an engineering perspective and creating very good/performant/useful products. There's a lot of credit in doing that well.
