>I wish developers would stop equating "complicated" to things "I don't understand".

The argument is a bit more about evolved than that, but flawed nonetheless. The argument usually invoked for Go is that, by eschewing selected language features, it prevents developers shooting themselves in the foot with unneeded complexity introduced by faulty abstractions.

I get the argument. I have seen my fair share of dug-out-from-hell complex projects. What the argument misses though is that not all abstractions are faulty. Computer science, as most science, is a game of ever increasingly abstract reasoning. If implemented correctly, the more abstract the better. The endgame is "Computer, build me a Mars round-trip ship".

Abstractions are good, when well written. They allow us to think on a higher level. Think of them as a fixed learning cost replacing a variable development cost.

Go kind of throws out the baby with the bathwater.

I think nobody would argue against that endgame, in the broad strokes. But I think Go can be understood as a response to [what the Go developers perceive as] overly expressive languages, languages that have overstepped our ability to responsibly abstract details, languages whose abstractions hide details that are still important and necessary to make explicit.

Go is "lower level" in that it purposefully eschews those abstractions, but I think it does that successfully, without a significant loss in expressivity, and with a more-than-commensurate gain in understandability, maintainability, performance, etc.

I agree. That is a correct reading. Where I do not agree is on the assumption that a basic feature set can be construed as a simpler language. While true for the language proper, it isn't true for real usage of language plus libraries.

Take operator overloading. It can be used to create hellish code. It can also be used to create great libraries (numpy for instance). Because of the danger of hellish code, Go makes it impossible to create numpy in Go.

In the end, while Go is simpler, a numpy in Go would be more complex[1], because the language is not expressive enough. The simplicity argument, while true for the language proper, is false for advanced usage.

[1] For example, you can't write Ma * Mb, but must remember the dot product method name.

Is it necessarily a good idea to make Go into a number crunching language?
I have no idea, but that is irrelevant. It is an example. I'm sure you can imagine others in the use case you define for the language.
