"In our industry, every technology generates what I call a “galaxy.” These galaxies feature stars but also black holes; meteoric changes that fade in the night, many planets, only a tiny fraction of which harbour some kind of life, and lots of cosmic dust and dark matter.
Examples of galaxies are, for example, .NET, Cocoa, Node.js, PHP, Emacs, SAP, etc. Each of these features evangelists, developers, bloggers, podcasts, conferences, books, training courses, consulting services, and inclusion problems. Galaxies are built on the assumption that their underlying technology is the answer to all problems. Each galaxy, thus, is based in a wrong assumption."
