I went to a Java One Conference during the spring of 1997. There was a panel discussion that included the following: James Gosling (creator of Java), Arthur van Hoff (wrote the first commercial Java compiler), and Bill Joy (BSD Unix, vi, Sun Microsystems). The following question was asked by an audience member: What Java development environment do you use? Here are the responses.Gosling.......emacs van Hoff......emacs Joy...........Unix shell
Later that day, I attended the Software Developer's Conference that was going on at the same time and went to a keynote on
C++given by Andrew Koenig (C++ guru). Koenig was using his laptop computer and on the task bar at the bottom of the screen was a button labeled emacs.
Upon returning to my job, I decided that I was going to start using emacs. It is truly an amazingly powerful editor, but I have been using the vi editor for so long that I found learning emacs difficult and my productivity almost fell to zero. As a result, I gave up on emacs and concluded that not learning this text editor was one of the biggest mistakes I've made in my computing career.

At the 2002 CPSR Conference I observed Simson Garfinkle using emacs.
