Why is the future of Humanity so uncertain?

We have made remarkable advances in the last 50-60 years. I can honestly say that our technological advances will go beyond our expectations, but at the same time the future seems rather uncertain for the human race. The reason is not because of one or two problems, but a chain of issues that might keep us from going further.

Yes evolution has allowed us to adapt to the many changes the earth has gone through but let’s look at it this way; the earth is estimated to be 4.56 billion years old. You might have your perspective of how old the earth really is but the way I see it the earth is aging, you can tell by the environmental issues that our planet has, yes we in part accelerated some of them but they have been happening slowly way before humans were around. Some scientists even believe Venus was at some point, very similar to earth until its own atmosphere created the last stage of the global warming effect, not allowing heat to escape and cooking it self in hellish temperatures

Now let’s take two products humanity would do a lot more without. If we put the alcohol and marijuana industry together we get somewhere around 205$ billion a year. If we were to put that money into space research, medical research, energy sources research, over one decade we would certainly begin to colonize space, see higher medical advances and let’s not forget find more stable energy sources other than oil. Now what would happen if we add the tobacco and video game industry? Even more progress in less time. What has stopped us from doing this? it’s all in the necessity.

Companies such as Apple, Microsoft, Google, Amazon (just to name a few), have done many things once though to be only possible in science fiction. Today we have millions of books at the touch of our fingers, we can find information about any topic almost everywhere at any time using our many technological devices. From the way that sounds space travel shouldn't sound so sci-fi, but the problem is as long as we don't have an advantageous reason to explore space , we are bond to read our fictional books to imagine it.

The point I'm trying to show by bringing up these big companies is, that they are responsible for many of our futuristic gadgets, and we are responsible for funding their research. You see if by any chance these gadgets did not catch our interests, they certainly would have found another branch of technology they could exploit or develop in order to have us, the costumers, buy from them.

Wars amongst ourselves can be traced back to the beginning of man. The problem is, instead of killing each other with rocks, we now have nuclear weapons. How many nuclear weapons does it take to destroy earth? Around 20. But let’s take into consideration that this type of technology keeps advancing and what now takes 20 bombs turns into 1. Yes is a scary though, and yes as long as we exist is very probable we will indeed keep fighting, we might as well never settle our differences and destroy ourselves.

As long as we exist we will have politics, and they will always be corrupted. There are exceptions to this, but you have to see it this way. Is in our mentality as humans to always aim to satisfy our necessities over everyone else's. So we will never have a system in which all individuals benefit and can work towards a common goal. So as long as political leaders shall exist they will always attempt to satisfy their benefits or their groups before anyone else, like you and me.
