People will forget - like we eventually forget about everything - but the information doesn’t have to disappear from the internet.

Have a website, blog, etc? Write about your experience, what you saw other people doing, the reactions, what politicians did, what you felt, etc. Archive the pages on the usual archival sites, so something lives on even after you die.

Just like some people went back to read what the newspapers wrote about the “Spanish” flu 100 years ago, someone is likely to get back to what we wrote/filmed/saved during this pandemic.
