BTW, there's a small small-world coincidence, between a desire for an Emacs-based super IDE, and the original article...
The desire for an Emacs-based out-of-box power-user IDE was how we got Lucid Emacs, aka XEmacs (which was one of the two big forks of GNU Emacs with GUI innovations that GNU took a while to catch up with)...
...from JWZ, et al.'s work on the Lucid Energize IDE for C++...
...and JWZ worked for Norvig early on...
...and Norvig was at Harlequin...
...and Harlequin acquired at least some of Lucid's IP.
