Computers are very powerful tools, but in the simulated world of the computer, everything has to be calculated.

Margaret Wertheim's quote reflects on the dual nature of computers as both powerful and limiting. She acknowledges that computers are incredibly powerful tools that have transformed many aspects of life and work. However, she also points out a key limitation: in the simulated world of the computer, everything must be calculated. This suggests that, despite their vast capabilities, computers can only operate within the boundaries of the data and algorithms they are given. In this simulated environment, the computer is bound by the rules of mathematics and logic.

The idea that "everything has to be calculated" highlights the difference between the natural world and the virtual world created by computers. In the real world, things can happen spontaneously or unpredictably, but in the digital realm, every action or process is driven by calculations, whether it's the movement of pixels on a screen or the way complex systems are modeled. This emphasizes that computers, while highly efficient, can only simulate processes that can be broken down into quantifiable terms.

Wertheim’s quote also touches on the concept that, although computers can mimic and model real-world phenomena, they cannot fully replicate the unpredictability and complexity of the physical world. The phrase "everything has to be calculated" points to the nature of the digital universe, where every interaction is based on mathematical precision, rather than the nuances or uncertainties inherent in natural systems. In this way, computers are powerful, but they are still limited by their own capacity for computation.

The origin of this quote likely stems from Wertheim's background as a writer and science communicator, with a particular focus on the intersection of science, art, and culture. She often explores the implications of technology, mathematics, and human creativity. This quote reflects her nuanced view of how computers influence our understanding of the world, both expanding and constraining our abilities to simulate reality.
