At first, I thought this was going to be about the Solid Project (which is sometimes stylized as SOLID) by Tim Berners-Lee. It's not. That would have been fun.

At first, I thought this was going to be about the Solid Project (which is sometimes stylized as SOLID) by Tim Berners-Lee. It's not. That would have been fun. Regarding SOLID principles being outdated, I disagree. The high level concepts of SOLID are good and just as relevant as ever. While the author proposes that code is now less risky to change, I would argue that the asynchronous, distributed systems that we often work with today are significantly more complex and error prone. The world also got hooked on dynamic languages for the past couple of decades, although it feels like that shift is slowly reversing. Software bugs have become a routine part of daily life, partly because there's more software but also because we build that software more haphazardly to achieve deadlines for ever expanding sets of features. Today, a large number of developers lack proper education or training and have relatively little experience. We work in teams where there's a lot going on besides writing code and there's more distraction around us than ever before. To me, there's no shortage of reasons to worry about changing a line of code. I spend a lot of my time trying to understand and reduce that risk so that I and everyone around me can be more productive in the long run. The SOLID principles are a useful guide in that effort. That said, you may want to update your interpretation of SOLID within the context of your latest coding practices. For me, that meant applying SOLID to functional programming. At first this seems odd, since much of the language around SOLID implies the use of classes and object-oriented programming. But it turns out there is a lot of overlap between the philosophies of SOLID and functional programming.
