Who will remember you in 100 years?

Is it possible to remember someone without having shared experiences with that person?

I don't think so.

Otherwise you're just remembering a short list of their most significant accomplishments and not really the person themselves.

So if no one is alive who interacted with me in 100 years, then, by definition, no one will remember me. A few people might recollect my accomplishments, but it will only have been done through 3rd party accounts and documents like my notes/books or photographs.
