Kay’s Vivarium started to take OO in the direction of emergent system behavior. While suitable for social phenomenæ like the Internet, it gives pause when considering Tony Hoare’s admonition: "I conclude that there are two ways of conntructing a software design: 1. Make it so simple that there are obviously no deficiencies 2. Make it so complicated that there are no obvious deficiencies. The first method is far more difficult.” We’re still stuck with writing programs to deliver to the mental models of businesses and their stakeholders. While Kay took the emergent path, MVC took a human-centric path.
The open sourced trygve language is the world’s first attempt to create a language that faithfully implements the Data-Context-and-Interaction (DCI) paradigm pioneered by Trygve Reenskaug (inventor of MVC, too) and Jim Coplien (who proposed a bit of OO thinking in his Advanced C++ 25 years ago). In this talk we’ll give a glimpse of what OO is all about and talk a bit about how trygve supports it.
