I was practically laughing while reading this. We think we are smart but not smart enough. Also, we humans often believe that our smartness has to do with what you can get in life over other or how manipulative we can get towards life situation to suit our purpose. Looking at the endless war amongst humans of different countries over what exactly? Why can't humans live in harmony and peace at all times? Even though we all know that no man is perfect, can't we live together as one where no one would feel less inferior or weaker than others. The most powerful people of the world and the riches are the ones determining what work and what does not.
I do agree that if people were truly more intelligent, not just smart in the usual way but wise and deeply aware, we would stop doing things that harm ourselves and others.
Most fights and problems in the world come from people not thinking clearly or not seeing the bigger picture. It is always who gets most of it as they don’t often care who get harm in the process or what got destroyed. I also like the idea of "enlightened self-interest," doing what is truly best for ourselves and everyone else. If we could all think like that, the world would be much better. It won't just be an endless rat race who finds ourselves.
here is nothing technical stopping us, other than our own stupidity.
Wisdom is having good judgement, based on experience and knowledge. Being really smart gives us the knowledge, the ability to learn from experience well, and good judgement based on it.
