It's less an opinion about constellations than constellations as an example of knowledge people shouldn't worry about "losing" or being "disconnected" from. I imagine most people have a cognitive burden that's heavy enough with things they genuinely need to know without being expected to manage constellations, TV schedules, discrepancies in the Synoptic Gospels, the lyrics to "Time After Time," or how to fry a turkey. You can look all of it up when it matters, and your experience will not be much diminished.
