“Nostalgia can have an intoxicating and powerful effect. Looking back through rose-tinted spectacles can create false pasts that cherry-pick only the very best, while ignoring the worst and the mundane. While harking back to a previous golden age often triggers warm memories of supposedly better times, the process can be deceptive, misleading and wrong. In fact, today’s world is better in almost every single way than the world of the past.”
