There has not been a single moment in the history of mankind where significant change has not occurred. In the earliest stages, natural events (droughts, rains, fire, eruptions...) made entire peoples change their customs and look for new settlements.
A couple of centuries ago the industrial revolution changed all the dominant paradigms and today technology is transforming the world.
What I want to say is that yes, of course, social codes can be changed, have been changed, and will continue to be changed. It is not something new. The pandemic that we experienced in 2019 had its predecessor in 19018 and the latter also had one.
Throughout history there has always been a trigger that drives changes, in some regions it is faster to observe them, in others it takes a little longer, but in the end, it arrives.
For example, in the 1980s almost no one had a cell phone, even in some societies, those who did not have one made fun of those who used those devices. Today it is practically impossible to live without them.
The question is not whether or not the code can be changed, we must ask ourselves how long it will take humanity to make the change and what will be next.
