I don't think the whole industry chooses its tools randomly. I think that in the long term, if a tool emerges from the dust it's because of some actual reasons. If the simplicity of Go will win against the complexity of Rust, for example, I think we should think about the reasons. In my opinion the problem it's not about Go limits, but instead is about our perspective as developers using our tools. We do really need complexity? We do really need oop everywhere? If the answer will turn out to be "no", I will need to change my attitude toward Go.

It may not choose entirely randomly, but that doesn't mean that it chooses reasonably. You mentioned OOP everywhere -- a philosophy that's driven several dominantly popular languages and has been seen as a mark of professionalism. If the industry is any guide, Go's break from the norm here already calls that decision into question.

(I happen to think this is one of several areas in which the industry is wrong, but then again I don't see the industry at large as particularly rational.)

> We do really need complexity?

No software developer wants complexity, every software developer is trying to manage and limit it to the extent of their resources.

The question is whether language simplicity leads to software simplicity.

It seems apparent Go's designers believe this is the case, and have offered a simple-ish language on a feature diet that avoids much in terms of type expressivity or facilities for abstraction that rise to the level of augmenting the language itself.

I think this can work for some problem domains, particularly one that is closely-fitted to built in types and libraries. But once your problem domain isn't close to native language facilities any more, you're forced to write more and more code to get around the limits of the language's expressivity. That ends up being more machinery and surface area to keep track of interactions between... which, in my experience, is where complexity creeps in rather than having to understand language features.

If rationality were a requirement for progress, progress wouldn't exist. The beautiful fact of evolutionary processes it's that rationality is not necessary. But I digress...

Needs change with time. In the current context, if Go is an improvement in some tech areas I think it will get some degree of success. Otherwise I think will decline after the first hype.

By the way, I agree with you about writing more code to overcome language limits. The hope here is that using idiomatic Go you will end up, no matter what, with a reasonably understandable code base, even for libraries and tools. It's a goal, I don't know if reachable or not.
