Title: Thermodynamic Computing
Abstract: Concepts from thermodynamics are ubiquitous in computing systems today –
e.g. in power supplies and cooling systems, in signal transport losses, in device
fabrication and state changes, and in the abstractions and methods in machine learning.
In this talk I propose that thermodynamics should be the central, unifying concept in
future computing systems. In particular, I suppose that computing systems of the future
will thermodynamically evolve in response to electrical and information potential in their
environment and that thermodynamic evolution is the unifying idea that addresses the
central challenges of energy efficiency and self-organization in technological systems. I
present a few results from a novel thermodynamic neural network model that addresses
the core assumptions of this approach concretely. Although the talk focuses on the
domain of computation, the ideas are generic and derive from simple observations of the
everyday world. A key conclusion of the work is that causation is the product of
evolution, an idea that inverts the current philosophy of computation and challenges
many common assumptions about existence.
