You have it reversed. If it is already true that being more symmetrical, imposing and pleasing is advantageous for negotiations, then the future in which we have the tools to counter that bias is getting less sad.
You can make a similar argument that the wide availability of soaps and deodorants reinforces biases about how people should smell. While that's true, the fact that anyone can easily match those biases reduces the opportunity to discriminate and makes those biases less of an issue.
You can make that argument, yes. I can deconstruct it by arguing that not everyone can easily match those biases - I bet there are still plenty of places on Earth where soap is surprisingly difficult to come by.
That side issue does not have much to do with the video issues under discussion, though.
I shudder at the thought of a world in which always-on lies about your appearance become standard practice.
Have physical reality and truth really become irrelevant?
They have been for quite some time: Cosmetic Surgery.
I remember watching a TV show years ago about a woman who had had lots of plastic surgery, found the man of her dreams, and was now pregnant. She was afraid the baby would come out looking totally different than she did, because she had physically changed herself so much, and her husband would leave her over the deceit.
At the same time, with cosmetic surgery, you are changing physical reality. Someone has sliced up your body and reconfigured it to be more what you want.
So it's not necessarily a "lie", as such.
Like I said, though, I see what you're getting at, and it's a valid point.
Since this has gotten to the point where we need to be precise with the language: they are not the tools for eliminating the existence of bias. They are tools for countering the effect of bias in particular instances.
I think you missed your parent's point. Let's examine a related case: fashion models. The industry has been manipulating images for years, to make models skinnier, whiter, removing blemishes, etc. In your language, these are tools for eliminating the effect of bias for the models. The impact that's had on our society is well studied: biases have been disastrously reinforced.
