Take pictures and make notes of the mundane. Modern social media and before that, "family" photography focuses on the highlights and best moments of your life, and some of it (instagram influencers) focus on a fictional, idealized lifestyle with a goal of self- and brand promotion in mind. And everything is very fleeting, there's tons of pictures of cats on my phone for example but all it takes is one accident and it's gone (although I have backups set up). But a lot of pictures are lost because of a lack of physical prints.
Random business idea: Microchip or negative photo printing. Send your phone's camera roll to a company, they send you a physical, archival version back that can either be printed like regular photos, or viewed through a viewer. Has to be physical and visual though.
I'm sure there's services out there for digital archival as well.
