Symbolics Lisp Machine and Genera demo

The go-to demo whenever HN discusses what Lisp machines were like and what modern shells and editors lack.

Symbolics developer Kalman Reti gives a short introductory demo of a Symbolics Lisp Machine running Genera in an emulator. It shows the context-aware command line, typed on-screen objects, and the live-editable system, including swapping in a C-compiled JPEG decoder.
