DESCRIPTION
Simon discusses how a simple math problem led him to discover the binary system 55 years ago. He explores how to maintain the essence of computational thinking in an era where AI can instantly solve coding problems, emphasizing concrete, motivated contexts over abstract algorithms.

The discussion spans from elementary programming to his unique role as a computing fellow at Epic Games, where he works with CEO Tim Sweeney to design the Verse programming language, proving that even big companies can prioritize denotational semantics over quarterly profits.
