RubyTalk
A small open-source experiment from 2013, inspired by Alan Kay’s Smalltalk and the long-standing idea that the computer should be a medium for thinking, not just a place to run programs. RubyTalk let you poke at live Ruby objects, inspect them, send them messages, and treat the running program as the workspace.
It was a love letter to Engelbart and Kay more than a serious tool. I still think the highest-leverage AI work happens at the same seam — the handoff between human and machine — which is part of why I spend so much time on Work Context Protocol now.
