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?
Drugs. The prohibition of psychedelic substances in particular is looking more like a crime against humanity since we are rediscovering their therapeutic properties in the west (that shaman have known for mellenia).
Discussion on the topic of mental health. Virtually nothing was known about mental health until very recently. We are the first generation that even talks about it. Therapy didn’t exist in any practical and organised sense for my mother’s generation. If you got PTSD during WWI, it was a death sentence because your own frigging side would shoot you.
