💡 BREAKTHROUGH INSIGHT
|
||
================================================================================
|
||
|
||
"Intelligence is not a software problem to solve with bigger models on faster
|
||
hardware. Intelligence IS a thermodynamic phenomenon—the process of organizing
|
||
matter to minimize surprise while respecting fundamental physical limits.
|
||
|
||
The Landauer bound—kT ln(2) ≈ 2.9 × 10^-21 J per bit—is not merely a
|
||
curiosity. It is the foundation of all intelligent computation. Current AI
|
||
operates ~10^9× above this limit. The future belongs to systems that approach
|
||
thermodynamic optimality."
