I guess Kubernetes doesn't count as Google pushing it then.

It is officially "not ready to use", it isn't a strawman as people keep complaining about nothing.

Kubernetes is written in Go (-ish. More like written in Java using Go syntax, especially in its early days when you claim it did some kind of pushing). But what kind of push are you dreaming up that it offered? If anything, Kubernetes leaves you to question if you ever want to write software again. The idea that it made anyone, let alone legions of people required to make something a "success", think "This is great. I should write my program in Go too!" is laughable.
