I don't think it's going to go anywhere (heh) but I do think it will find its niche - you can see this in things like Docker and Kubernetes.

It serves a useful function, being somewhere between a pleasant, slow and somewhat less dependable scripting language like Ruby or Python, and a fast, dangerous language like C. It's perfect for writing lower-lever distributed systems, and is terrifically boring in a way that a reliable language designed to handle these sorts of systems should be.

So I don't think it's going anywhere. It's great for writing the plumbing that powers everything. I don't want to build web apps with it, but there are plenty of other options for that.
