Hi:

I have a novel idea "Digital Twin applied to Software". See attached slides.
It points to the future of improved programming productivity and
reliability.
Let me know what you think.

Thanks,

Abstract

Digital Twin applied to Software
Aik-Siong Koh
askoh.com

There has been a major dichotomy in computing right from the beginning:
Statically Typed vs Dynamically Typed programming languages. The former
languages produce fast executables but are inflexible to program. The
latter are just the converse. This dichotomy has been frustrating to
programmers who always feel they have to make sacrifices when making a
choice. It also often leads to futile language wars. The Digital Twin
concept was introduced in engineering where a physical system is modeled
digitally in geometry, simulation and other information. The concept has
proven so successful that it is being applied to almost everything in
engineering from simple mouse traps to complex whole cities. It occurred
to the author that this concept can be extended to software too. For
example, execution in C++ is famously fast. But development in C++ is
notoriously difficulty because of language complexity and long build
times. A flexible digital twin can be a program written in Smalltalk
which is famous for live programming. "Development at the speed of
thought" is the motto and is real. What is gained by this duplication?
Firstly, the flexible twin can be use to explore new algorithms,
features, solutions and fix bugs quickly. Only desired codes are
translated to C++ manually or automatically. Secondly, the two programs
can check each other so that bugs are reduced significantly. These two
gains will define future programming productivity and quality. The
Digital Twin concept will also drive the automatic translation of the
flexible language to the fast language.

Bio

Dr Aik-Siong Koh has a PhD from The University of Texas at Austin where
he programed in FORTRAN to simulation mechanical systems. While teaching
at Texas Tech University and Nanyang Technological University, he
developed interest in Multibody Dynamics. To develop his own Multibody
Dynamics simulator, he researched for the most productive programming
language and discovered Smalltalk. The live programming capabilities of
Smalltalk permitted him to build a successful simulator which he then
proceeded to commercialize. His later experience with C++ at Mechanical
Dynamics and MathWorks gave him the idea of Digital Twin for Software.
