Honestly, in some areas it feels like adding libraries only adds more problems and a lot more cost to integration than one expects beforehand.

I'm not saying libraries are bad in general. But when it comes to dependencies I have seen no sign of change since the left-pad debacle and that concerns me, not only because I think fixing broken dependencies and builds is one of the most frustrating things to do in development.

Preventing problems is even better than solving them, and in contrast to at least some colleagues I know I tend to prefer to "waste" time writing some of my own code, because at least I know how to debug or adapt that.
