I’m not convinced that limiting expressiveness (for example by not supporting generics) will make software easier to read and maintain. For smaller programs that might very well be true, but for me personally, having more expressiveness makes it easier to navigate bigger code bases because you don’t have to trudge through code duplication, unnecessary boilerplate etc.

I agree. The limited expressiveness in Go also worked as an advantage because of its simplicity. Additionally, as the article mentions, the lack of lambdas made the syntax less convenient. For me, it struck a good balance before generics and other features were added.

You are free to not use them.
