I am at a family gathering around christmas. Several aunts, an uncle, and my (in actuality, late) grandfather are there.
It is somewhat the future.
I have a newish smartphone and am taking selfies with my family. I notice something strange; in the photos, everyone (my aunts and I) looks a little different. Our skin is more glowing, or less-wrinkled, or generally younger-looking. Our hair is less gray.
In my dream I realize I am lucky to be around my grandfather. He does not understand selfies but I convince him to get in some with me and an aunt.
I keep taking pictures but his head will never appear in them. Just an empty collar. My aunt and I are there but have the strange airbrushed look.
I get curious and start googling for this symptom. It turns out that the camera software on my Facegooglebook smartphone is "airbrush only" in which, for each human in a given photo, facebook scours the internet for every single picture of that human and constructs an "idealized" version of their head. This is considered a feature or improvement.
Since my grandfather has only ever been old on the internet Facebook decided it was best to just leave his old, wrinkled face out.
I get furious and start writing blog posts about how awful this is. I rant about Facebook's ageism and how it enables a culture of self-hatred and terrible body-esteem.
I realize that it's too late and that all software is proprietary and that things can never change.
