What social taboos that exist today do you think will not be around in 100 years?
I was reading a book on social life of the upper-middle class and new rich of the American 1920s and realized so many things we now do proudly were considered socially taboo back then. This was especially the case for clothing, makeup, women in certain public spaces, etc. What do you think will be different in the 2120s? Or maybe even the next 50 years?
I would presume that in 100 years, if humanity still exists, we'll be deep into a dark age, so there likely won't be much in the way of widespread taboos at all. Individual clans and tribes will undoubtedly have their own taboos, but there's no telling what they might be.
What makes you think that a global crisis would reduce humanity to tribes and clans? Isn't it more likely that desperate times result in something more like a global government and more systematic enslavement of humans? How could the owning class ever pass on the opportunity of not having to work and instead utilize their workers as efficiently as possible?
