Energy, agriculture, transportation - all built on the unintuitive building blocks of physics, and our approximate understanding of the universe. The clean abstraction layers and separation of concerns in IT is unparalleled, with powerful positive feedback begetting further innovations.

Applying advances to other fields also grew economies of scale rapidly, supporting innovation while barriers to entry were low. We're now approaching the end to low-hanging fruit and maturing into the consolidation phase, as further innovation requires greater capital and time commitment.
