Complex Information systems, like DBMS to store data, languages to process data. ERP to do business, sending and receiving mail, Chat to send and receive quick messages etc. are made up of many programs. These programs are compiled and stored in a instruction stream in RAM. These programs are executed by microprocessors. These processors take instruction, from the instruction stream, executes that instruction. While executing, data in the data stream (again in RAM) is manipulated.

The present day programs and processor, has its roots in the computing theoretical foundation like Turing Machine , Von Neumann architecture and lambda calculus. The present technology is based on the premise that anything computable can be computed on this abstract Turing machine model. The Von Neumann architecture is the engineering model of this Turing machine. The language that programs these models are based on mathematics i.e. lambda calculus. This makes present machine and languages Computation By Design

Due to the miniaturization of devices and the increasing networked nature of the information topology, the application demands now have moved away from just pure computation and data processing. Information systems are expected to be Secure by Default and Offer Privacy by default even when serving new sharing and workflow demands. Vulnerability of information systems, Poor software productivity, Poor information systems quality, Increasing arthritic conditions of our software systems, Lack of privacy primitives in our software systems and the Data intensive nature of our AI systems (This reflects the past and is not conditioned for the VUCA world) are the symptoms of our reliance on our present Compute By Design based systems.

Quoting Andrew Grove, we are at an inflection point in computing. compute by design has reached its limits. We need a new beginning.

Computation By Design transforms data.
