Smalltalk appears to be little more than a footnote in the history of popular computing languages. But I've yet to hear anyone speak badly of it. The design seems to be technically sound. Its OOP implementation seems to have influenced Objective C and pretty much every OOP language that came after it. It appears to be well-beloved by developers.[0] It has its own virtual machine implemented, which should make it portable.So why did Smalltalk die while Objective C, C++, and Java all gained widespread adoption and thrived?
