I understand what the guy is saying, but this is equivalent to art students discussing the technicality and construction of canvases. Even if you select the best canvas in the world, it does not make your painting better.

I think that too much of writing about programming is focused on the details of the programming act, and too little on the result of the programming.

Reading about finding and learning a programming language is like reading about an artist choosing a brush. Reading about the technical details of someone scaling a Django app on a single server to serve 1000 concurrent requests per second is like seeing the finished artwork.
