The Wet Codebase” by Dan Abramov

So what happens is that developers learn best practices from the previous generation and they try to follow them. Because there were concrete problems and concrete solutions that were born out of experience. And so the next generation tries to pass them on. But it's hard to explain all this context and all this trade off, so they just get flattened into these ideas of best practices and anti-patterns.

And so they get taught to the new generation. But if the new generation doesn't understand the trade offs and the reasons they came to these conclusions, they don't have the context to decide when it's actually a bad idea and how far can you stretch this. So they run into their own problems from trying to take these best practices and anti-patterns to the extreme. And so they teach the next generation.

So what to do about it?

I think one way to try to break this loop is just when we teach something to the next generation, we shouldn't just be two-dimensional and say here's best practices and anti-patterns. But we should try to explain what is it that you're actually trading away. What are the benefits and what are the costs of this idea?
