We have never built anything complicated enough to self - replicate or self -repair that could last a hundred years. We have never built a biosphere that can exist in a self contained manner for a hundred years. I am not saying we won't but you are assuming we will figure out how to makes something that will maintain its message integrity for a hundred thousand years and then we will have the energy or the ability to shrink it enough to be able to send it off to some life supporting star. We have only had complicated writing for a few thousand years. People have wondered if a technical civilization existed on earth a hundred million years ago would there be any thing around now as evidence. If it takes a million years of travel in the freezing, radioactive vacuum of space to reach another life form, you don't know that humans will be around long enough as a civilization to figure out how to actually build the thing that you are describing. I hope so, but I don't think its been proven to be possible yet.
