Human progress has no inherent limits, and every problem in the universe is solvable through the creation of good explanations. We are at the very beginning of an infinite journey of knowledge creation.
A good explanation is structurally hard to vary, meaning its core components cannot be arbitrarily altered without destroying its predictive power.
Human beings are universal explainers and constructors, possessing the cognitive capacity to understand and transform anything in reality that the laws of physics permit.
True progress does not originate from inductive observation, but rather from bold, creative conjectures that are subsequently subjected to rigorous testing and criticism.
