Idk, but I’m sure that in at least 200 years genetical modifications will be accessible if everything goes fine. Probably it will apply to skin tone and facial features and there could be a strange variety of new colors or most people would pick whatever is considered ‘the best looking’ features in 300 years.
tbh the idea of having the choice of changing genetics sounds good, but it’s impossible to know what will happen in 300 years.
At least that is what I think possible in the next 300 years.
