OOP has been a massive step in the wrong direction for programming. To take your example of DI, in Clojure, dependency injection can be done in a few lines for the whole application. In Java/C++/PHP and other languages that use constructor or setter injection, it requires all the code to be rewritten around a DI container, requires many modifications just to get to the point of writing code that actually does something. There is no comparison. We're talking a dozen lines of code vs. dozens of classes spread over dozens of files to achieve the same thing. Minutes vs. hours spend on boilerplate. I wouldn't call this a knee-jerk reaction, but rather a well-thought out reaction to a few decades of OOP. When I started programming 25 years ago, I felt OO was a misguided idea but I was a novice and couldn't put my finger on it. Now, it's clear to me that all OO does is add unnecessary complexity and simply cannot model real life at all. I don't see a single problem that it solves better than either procedural or functional paradigms. Those paradigms have a lot less boilerplate, are a lot easier to understand, and can be learned much more easily. Giving precedence to code over data, IMO, is a huge, irredeemable mistake. That's literally the mistake OOP is built on. Data should be a first class citizen in any system, yet it's a second or third class citizen in OOP. It is hidden in objects, processed only by limited certain methods, and generally hard to work with (you can have data only objects, of course, structs, but then you're back to a procedural paradigm). I find myself spending anywhere from 25-75% of my time in OOP languages writing boilerplate to get the right objects talking to each other and the rest writing actual business logic that matters. In something like Clojure, time spent writing boilerplate is around 5% at most. I'm using Clojure simply as one example. I'm sure there are other functional and procedural languages that are also good examples.
