According to the others on this thread it's related to the date when Kubernetes was released. It wasn't clear to me, but thank you, I think you raise another good point.
Thanks. I just wanted to know what the author meant; it wasn't obvious that I needed to Google the quote to figure out the meaning. I certainly hope that I wasn't adding any FUD to the discussion.
Thank you. I'm sorry that you feel like I was trashing the tech. I really didn't mean to come off that way by asking a question about a statement that the author made.
