Tesler's Law of Conservation of Complexity: Every application has an inherent amount of irreducible complexity. The only question is who will have to deal with it - the user, the application developer, or the platform developer? - Larry Tesler (ca. 1984)
With a good programming language and interface, one - even children - can create from scratch important simulations of complex non-linear systems that can help one's thinking about them. - Alan Kay (2016)
An evolving system increases its complexity unless work is done to reduce it. - Meir Lehman
Any sufficiently complex system acts as a black box when it becomes easier to experiment with than to understand. Hence, black-box optimization has become increasingly important as systems become more complex. - Google Vizier: a service for black-box optimization Golovin et al., KDD'17
We're more aware of simple processes that don't work well than of complex ones that work flawlessly. - Marvin Minsky, MIT AI lab co-founder
Tainter's Law of Problem Solving: As easier solutions are exhausted, problem solving moves inexorably to greater complexity, higher costs, and diminishing returns.
The endogenous nature of [the] buildup of complexity eventually makes the system fundamentally illegible to the human operator - a phenomenon that is ironic given that the fundamental aim of the control revolution is to increase legibility. - Ashwin Parameswaran (2012)
It is time to unmask the computing community as a Secret Society for the Creation and Preservation of Artificial Complexity. - Edsger Dijkstra
You're not going to find the best algorithm in terms of computational complexity by coding. - Leslie Lamport
I have struggled with complexity my entire career. One of our key approaches for managing complexity is to 'walk away' and start fresh. Often new tools or languages force us to start from scratch which means that developers end up conflating the benefits of the tool with the benefits of the clean start. The clean start is what is fundamental. The simplest way of controlling complexity growth is to build a smaller system with fewer developers. - Terry Crowley
Successful programming is all about managing complexity. Managing complexity has many aspects. You can eliminate, avoid, simplify, hide or automate complexity, and so on. - Keith Bentley
The most robust programs isolate complexity in a way that lets significant parts of the system appear simple and straightforward and interact in simple ways with other components in the system. - Terry Crowley
