I just had the terrible realisation that, the world we live in now, in 40-60 years, will be considered "the old days".
We all have a specific image of what "the old days" feel like. But our modern era will be someone's old days. Our media that we see as present and developed, will become retro. Our culture for all its advances, will become dated.
I don't know what the future will be like when millennials are old, but the thought our world will be looked at as we do boomer/silent's, is scary.
