Sometimes: On CDH my private photo gallery has a clearly-named folder for FaceApp-modified photos.
For me, these images lessen dysphoria. Some philosopher said that “memory” and “imagination” are two words for the same thing. I dissent a little: regrets (and more positively, learning) come only from our memories. Plausible images of a fictional young girly me happily alleviate the possible real-world distraction today of a gnawing regret of a lost opportunity.
Not for Facebook or anything else public. This discussion here reminds me to update my possible photo at LinkedIn.
I have bought or declined particular clothes and colors after using FaceApp “face swap” to insert my photo into ads.
