There is an argument to be made that there could be a phase transition when it comes to the ability of understanding things. When you manage to write down your thoughts so future generations can build on prior work, and when you manage to formalize problems by abstract notation (math), and when you gain the capability of breaking down complex problems into small solvable chunks, then maybe, and I want to stress maybe, there is no limit to understanding things. On the other hand, there also may be problems with irreducible complexity, so it really could be either way.
