I think COVID really pushed the process forward. A lot of older and non-technical people learned to use Zoom, touchless payment systems, and online banking. Even for the folks who were already living a digital lifestyle, the lockdowns killed that last vestige of paper in their lives -- the shut-down libraries moved to digital lending, schools replaced a folder of papers with Google Drive and text announcements, the idea of bringing handouts to a work meeting became obsolete. Even handling paper mail was scary in the early days, before we had a clear handle on how the virus spread. In a lot of subtle and not-so-subtle ways, it all added up to an acceleration toward the post-paper era.
Just today, an exec at work told me his division is planning to eliminate all printing costs in the near future. All printing costs, both internal and external. Sooner or later, there's a tipping point where owning a printer is like owning a fax machine. See below:
I realized the other day that I'm there. One of my kids' extracurriculars wanted me to print and sign a legal form, and I realized that getting my home printer to work properly would actually cost more time and money than printing at UPS. So I ended up doing it there, which meant showing my kids that process, which means they now conceptualize printing as an unusual occasion worthy of finding a service to do it. Printers are going to be their generation's fax machines.
