The Red programming language is a notable successor to REBOL, designed by Carl Sassenrath, who is known for his work on the Amiga kernel. Users have shared mixed experiences with Red; while some find it intriguing, they struggle to fully grasp its concepts and build a mental model of its workings. There are concerns about its development trajectory, especially with a focus on cryptocurrency-related features, which some believe could detract from its core purpose. Overall, there is hope within the community for the eventual release of Red 1.0, to provide a more stable and complete platform for developers.
