"All physical systems can be thought of as registering and processing information, and how one wishes to define computation will determine your view of what computation consists of"

This quote by Seth Lloyd recommends that all physical systems can be seen as a kind of calculation. This implies that computation is not limited to the traditional definition of a computer, but can be found in any physical system. Lloyd's declaration implies that the definition of computation is subjective and can be interpreted differently depending upon the individual. For instance, some might see computation as the procedure of a computer system performing estimations, while others might see it as the process of a physical system reacting to its environment. Ultimately, Lloyd's quote suggests that calculation is a broad idea that can be analyzed in various methods.
