The whole concept of not knowing what you’ve got until it’s gone. Remember that song you used to hate hearing and now 20 some years later, you’d wish we’d be back to music like it because music today is too artificial and AI-powered? Remember nearly a lot of things you criticized and now have a soft spot for because everything now has gone to shit?
Yeah, that hits hard. What sucks is that sometimes, you don’t know for certain if you’re experiencing the best of things. But once it passes you, give it 1 - 5 years, you’ll know it.
Childhood that’s gone in what feels like an instant before you had the chance to appreciate it, and by the time you do enjoy it after the fact, from memory, the moment is already long gone, no matter how hard you cling onto the memory, its already in the past, you have no time machine to go back and re-do that again.
