Let us revisit the opening paragraph of The Hitchhiker’s Guide to the Galaxy:
Far out in the uncharted backwaters of the unfashionable end of the Western Spiral arm of the Galaxy lies a small unregarded yellow sun. Orbiting this at a distance of roughly ninety-eight million miles is an utterly insignificant little blue-green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea.
If I squint just right I can almost, almost talk myself into believing that smartwatches will be useful. But this is a personal failing.
