AutoCAD brought Lisp mainstream for mechanical engineers, architects, and so many other 'rocket scientists' that I believe Emacs pales in comparison. I was programming AutoLisp (automatic correction of trace and drill patterns for PCBs) on the machine which wasn't even able to build a decent Emacs in reasonable amount of time (PC AT/286 12Mhz with 2MB memory :-)). I was able to build myself an Emacs only after I got upgraded to 386SX 16Mhz with the whopping 4MB of RAM.
