I often tell my students that although we were born as humans, we have not truly become humans. Because we are mentally fragile, greedy, and violent. Nowadays, we seem to be becoming safer day by day. Especially in the present, I never feel safe. To be honest, on a personal level, I myself am also very depressed about our future and present. That is because of all the social or security-related reasons. It also seems to me that we have left the good times behind.
And "going back" isn't the answer, going forward better is. We just aren't going forward better at the moment.
