I'm afraid to read the article, but based on the replies, I can relate.
I'm different in that I'm on the pre-sales side of things. While I need to be technical and I do get in to the nitty gritty details of the gear, I don't have the stress of keeping it up and running. When (not if) it hits the fan, I can end up being the quarterback to a resolution but I'm not ultimately on the hook. Plus, I can push things on to support and development engineers if I have to.
So, when new stuff comes along, I need to learn it, but if I just learn enough to help sell it, I can survive. If I learn any more, my value goes up.
