Generics are useful for some purposes. But mostly they can be avoided in favor of simpler language constructs. Most Go developers understand the importance of using simple code constructs.

There are many experienced developers who (through long experience fighting C++) have come to understand that using a simple language (like Go or C) allows you focus on the algorithms and complexity of the problem you're trying to solve. This is part of the Go culture.

A junior developer might not understand this yet. He's still having fun finding obscure and convoluted contortions of the language that allow him to save little or no effort... not yet realizing that nobody gives a shit and he's wasting his time and the time of his coworkers.
