That came to mind while we watched a 1000-foot ship slowly slide into the Poe lock(*). The giant machine needs only a crew of 25 or so, according to the boat watcher and former ship engineer beside me (and the captain's job isn't all that well paid these days). Hard work, and dully unromantic for those who have to do it; but amazing to the rest of us. Watching it is even rather peaceful to those of us who don't have to worry about 2 1/2 foot clearances.
I heard the obvious joke a half a dozen times
