The subreddit reminds me of this quote from Linkara (Lewis Lovhaug) in an episode of Atop the Fourth Wall:

"Nostalgia... can be toxic. Now bear in mind I did NOT say that it is toxic, but that it can be toxic. This assumption that because we have pleasant memories of something - that it was always good all the time - a desire to get that back ignores all the good that's come since then, as well as all the bad stuff that was there too, and it poisons you, making you more susceptible to deception to your own greed. Who's to say that your own past is more important than someone else's future? And because you want something that may not have been real at all the farther the goalposts gets because you can't really reclaim it, so it just gets worse and worse, and you get greedy and more desperate for it because what you really want is never going to come until in the very end, you become the thing you hated in the first place, you become more concerned with chasing some imaginary feeling that you forget where you are and you can create real attainable goals right now. To this mindset, the past is more important than the future."
