Unless you're mailing letters, it's almost certain that your life is in "digital format". It sounds like you just don't use a calendar.
But surely you have an email confirmation for your movie, baseball, or event ticket. And maybe you texted or otherwise messaged with your friends who were going? Took pictures on your phone with them? Carried your phone with you when you went.
The argument is that you could potentially make easy use of these digital assets via an assistant that has secure, private access to them. As someone who forgets to use his calendar for social events, I'd love to be able to ask "what events are going on this weekend" and have it show me everything I've agreed to do via email/text message/3p messenger app.
I don't trust that a fuzzy automatism adds anything beneficial to that
Right. I meant I don’t make use of such digital assets. They are there because of tech giants, but i just don’t gain much from them.
