Hm. To be honest, I think to a neutral and external observer, the current state of humanity mightn’t look so appealing. There’s a lot of greed, hatred, delusion and ignorance. A very large percentage of our current population still lives in abject poverty. At any given time, there’ll be something like half a dozen armed conflicts in progress in different parts of the world. There are at present on the order of 13000 nuclear warheads available for launch (~90% of which in just two countries). Nationalism, militarism and various forms of religious and cultural extremism are rife everywhere. Even in developed nations with good education systems, the average person’s knowledge of scientific, philosophical, ethical, sociological and teleological concepts is at best rudimentary. Of course, our species has also achieved many positive things in the sciences, humanities, arts, etc etc - but it would seem to me that these sadly are not representative of our overall state of affairs, at least not at this point in time.
Would I, as being an advanced civilisation, and based on what I am observing here on Earth right now, be inclined to share my knowledge and technology? I think probably not. A ultra-sharp kitchen knife is a really useful tool that enables you to cook a delicious meal - but you wouldn’t hand it to a toddler, would you?
