Indeed the problems of the world are complex and that means solutions that work today may not work tomorrow. So humanity has to be able to evolve in it's problem-solving approaches. And we have to realise that it's not all these complex problems are meant for the government to solve. Some we have to solve ourselves as individuals. Or we might wait forever for the government who are only interested in making money for themselves.
Yet, individuals on average are getting worse at this, because we are all consuming from the same pool of content globally. Diversity should being thought and approach - we shouldn't care about sexual orientation or skin colour at all.
