Imagine Earth in the future. Technology is super advanced and people can change their genetics [and in particular their outward physical appearance] on demand, easily, for free, as many times as they want. I.e. technology exists such that a person can e.g. pull out their phone, go to their appearance settings, and change their height, build, skin color, hair style, eye color, etc., i.e. they have complete control over their physical appearance.
For now, assume that humans stay human, i.e. they do not alter their biology so much that they have wings, gills, etc. So they are still recognizable as humans but can have any human appearance they want.
Also, assume that by now the technology is ubiquitous so everyone is using it, i.e. it is not just a tool of the elite, but is used uniformly by all demographics.
The question is: Racism is a very complicated issue. But how will racism be affected by this ability to arbitrarily alter appearance?
On the one hand, if anyone can have any appearance, then you don't actually know what ethnicity someone was by birth, so in one sense no one has a permanent ethnicity and race is less relevant. [But it's very possible that people may have a special fondness for their "true" genetic makeup and physical appearance, so they may favorite this as one of their default appearances, and spend more tie in that configuration, and therefore still on average be more that wthnicity than any other].
On the other hand, people may take advantage of existing racial stereotypes depending on their activities: oh, you are trying to be recruited for the basketball team? Well change to your black person avatar. Oh, you got pulled over by the police, you want to be hired for that job, you want to rent that apartment, etc.? Change to white person. Oh you want people to assume you are good at math? Change to Asian appearance. Etc. You can see how users might try to take advantage of some other people's assumptions about race in order to benefit their activities.
Some people may switch to another ethnic appearance and intentionally misbehave in order to bring negative attention to that group.
So some behaviors will encourage racism while others may reduce it. What are some other effects that strengthen or reduce racism in this society?
