By 2011 Rust has a logo (basically its current logo), and it has a compiler written in Rust (a distant ancestor of today's main Rust compiler). It's approaching Rust 0.1 (released January 2012 apparently) which is a very different language from Rust 1.0 -- but that's a long way from "there was no Rust in 2011" to my mind.

The point is not a comparison with Rust per-se, but the fact that a better implementation of the idea was mathematically and/or technically possible; and the personal opinion that such huge footguns that the language accumulates over the years are maybe signals of having needed more thought to them before they were considered ready.

e.g. if something as simple of a inconspicuous std::move in the wrong place can break the whole assumption about move semantics, then make that impossible to do, or at least do not make it the default happy path, before you consider it production ready. What the heck, at the very least ensure it will become a compiler warning?

Hence the mention to Go and how they follow exactly this path of extending discussion as long as needed, even if it takes 10 years, until a reasonable solution is found with maybe small gaps, but never huge ones such as those explained in this article (plus tens of others in any other text about the language)
