Here's an attempt at thinking more positively.
The other day my brother and I were talking about movie rentals, and how the span of time those were relevant (between the critical mass of home VCRs and widespread adoption of streaming services) was only 20-25 years.
They seemed huge at the time—whether major chains like Blockbuster or the local independent ones that were charming spaces to patron and kept local subcultures together—but are a foreign idea to younger people, because they're really quite irrelevant now.
Things can come and go within our lifespan, including shitty periods of time. Not every change will be permanent.
