You move to dismiss what I have to say by framing me as closed to new ideas because of how you infer my age, in a roundabout way -- what an ugly, uncouth, and mean-spirited rhetorical move.

Either way, you badly mischaracterize generational differences in grieving and digital life. Gen Z and younger millenials are vastly more inclined towards memorialization of deceased loved ones and (physically & digitally) archiving their content than any generation. See also the uptrending of stated preference in burials over cremations in the same generation. There are many reasons for this but at least in part it is probably a reaction to the ephemeralization of both digital and physical life.

Also, my post was largely motivated by how OP brands their product. From their app store page and the blog post, it seems they will support photos, longer form content, and DMs. In such a setting, ephemerality needs to be in your face, otherwise you are setting up users for unpleasant surprises. It's common sense.
