I agree with you.

Complexity/computational theory strongly suggests that a system cannot compute anything beyond it's own inherent complexity. Put in terms of people, it is impossible to understand anything that is intrinsically more complex than our own brain. There will always be things that we do not, & cannot, understand. Maybe, if we are lucky & evolution moves us in the right direction, our brains may become more complex allowing us a greater insight to the universe & the interactions of all within it. That is, if those who believe they understand everything now don't destroy us first.
