Abstract

David Harel says a new generation of autonomous systems is on the horizon, and the world may not be prepared. Harel’s concern underscores the need to rapidly develop better means of designing and testing such systems.

His work has resulted in languages such as Statecharts and Live Sequence Charts. In his Inaugural Article (1), Harel and his colleagues lay out principles that they believe should guide the design of trustworthy future-generation autonomous systems, embodied in the term “Autonomics foundation.” David Harel.

How does that shift tie into the proposal you make in your Inaugural Article (1) for an Autonomics foundation? > Harel:In 1984 I did some consulting for a very complex avionics system in the Israel aircraft industry. I got hooked on what I …
