I too like boring tech and try and avoid shiny stuff. I'd like to refine this idea though: is it that I like boring tech because it's old and battle-tested, or just because it's old and I'm familiar with it? E.g. Bazel. Is it shiny new or is it boring old? It only made v1.0 four years ago, but it's based on Blaze, which has been developed internally at the Google mothership since 2006. To a Googler, Blaze probably seems boring - does Bazel, too?
