Good summary of Rust. I love the language. D's great, but it needs to decide if it's garbage collected or not! Never looked at Nim, but isn't it basically a one-man project? Rust has the advantage of being backed by a major corporation (albeit an SJW-infested one).

I agree that Rust would survive in some form if Mozilla went under, but it would be a blow. The long-term financial viability of Mozilla is still Rust's biggest threat, IMO.

The first two problems are to be expected of any new language (e.g., Rust, Swift). The third point seems backwards to me: isn't it good that it breaks with traditional paradigms? What's the point of making a language that's just a nicer C? Can you say what specific aspects of Go you didn't like, and why?

The type system is lightweight, and deliberately so. That may or may not be a weakness, depending on what you want from a language. I do consider it a weakness, but I can see why others may not think so (see Rob Pike's "Less is More" talk).

I don't use Java, so I can't speak to the speed comparison. I found it significantly slower that C++, that's for sure, but still much faster than Python.

And consider what you do get with Go:

1. Lightning-fast build times.

2. Built-in, easy-to-use concurrency.

3. The interface mechanism is cool.

4. Garbage collection (yes, it slows things down, but it makes coding so much easier).

I used and enjoyed Go for a couple of years. I switched to Rust recently, and am cautiously excited about it. But I still think Go is cool, and would happily use it again.
