The endless possibilities of knowledge

Although we humans, are beings with immense limitations we also have endless possibilities, and I would go as far as to say that all problems that we face and that we create could be solve with more knowledge. Given the fact that I start this article with a very bold statement, I will assume that my readers are starting to think in a series of objections to my absurd idea, but I humbly ask to keep reading, maybe you will agree with me at the end, and besides, my articles are generally very short.
To prove my point about knowledge I will start using cancer as a problem that can be solved with more knowledge, but even in the cases when a cancer can be cured anymore, it is still a problem that can be in a certain way be solved with knowledge. When you know that there is nothing that you can do to change something, you can at least learn how to deal with the feeling of impotence that emerge from this kind of situation. I'm aware of the fact that the line of reasoning that I'm using is creating an argument that can't be refuted, because every example of a problem that can't be solved with more knowledge, can be counter with an example of how to deal with the impotence cause by this, and deal with frustration and despair always demand knowledge.
Nevertheless, my point is that all the suffering in the world is cause by our blindness to other possibilities, or our inability to accept the world as it is. What I think is possible to create, is not a world without suffer and despair, but a world when at least most people are capable of escaping a spiral of bad feelings, a world capable of realizing the full extent of human possibilities, in synthesis a truly free world.
