The ultimate limit to AI growth may not be data or chips, but the literal boiling point of the Earth.

The Takeaway
If AI continues its current exponential growth, the waste heat generated by its physical hardware will eventually exceed the Earth's ability to cool itself. This paper frames the evolution of intelligence as a 'thermodynamic tightrope' where the laws of physics may eventually shut down progress to prevent ecological collapse.
From the abstract
The artificial intelligence industry is not an isolated economic phenomenon; it is the current physical substrate for a broader, multi-billion-year process: the evolution of an abstract "intelligence" on Earth. As computation accelerates toward a planetary-scale phase transition, the dominant discourse remains largely confined to algorithmic architectures, alignment, and silicon supply chains. But physics invariably asserts itself. When analyzed from first principles, it becomes clear that if th
