"Consider for example Hadoop. Nobody seems to know how to build Hadoop from scratch. It’s an incredible mess of dependencies, version requirements and build tools." And that's exactly what's wrong with a half of the software industry. Some people even take pride in thinking that having dependency hell is a good thing. A lot of build tools look like they are created by aliens to aliens with little thought of how the end user would use it. And if someone dares to say how crappy the whole thing is, they get dismissed for not being smart enough or simply lack dedication to spend unlimited hours trying to build some 500 line code.
