"Go is on the frontier of recency vs popularity (i.e. newer than all more popular languages, and more popular than all newer languages)" is honestly an "interesting" statement in its own right, but would be a distinction it has to share with Python, Java, some of JS/C#/VB/PHP depending on your popularity (and age...) metrics, and yes, Swift and Rust. And a long tail of very new languages, I suppose.
