I suppose that’s fair, but I’d argue against switching even being a primary motivation for anyone at Google, which is why I don’t think of it that way. You do have a point, though.

Without intimate knowledge of Borg, I can understand the successor discussion. With knowledge of what changed (i.e., was getting rid of borgmaster really that important to sacrifice that much perfwise?) I can’t even remotely fathom any purpose for Kubernetes other than what I’ve described. You, however, know far better than me. :)
