Unsolvable.

“We can't solve problems by using the same kind of thinking we used when we created them.” - Albert Einstein

Let's say Einstein is correct in this statement. Existence can never be 'solved'. I have thought about it a great deal recently, and lets say the singularity happens. AI creating simulated universes in order to find the answer to existence, and in turn them creating singularities and AIs that create simulated universes to find the answer. We can't solve problems by using the same kind of thinking we used when we created them. Every thought the brain has is the cause of an outside influence. You hear a loud noise and look in that direction because you heard the noise. We can never have a truly unique thought, just the perception of having a unique thought... therefor how are we going to solve the ultimate question?

We are just an unsolvable influence based ever changing existence.
