So, as Steve mentions in his post, Grok already exists. It's designed to work with all editors, including IDEs. IDEs exhibit ... how shall I say ... interesting failure modes ... on the Google codebase. Grok will benefit users of Eclipse and IntelliJ as much as it will benefit users of Emacs and Vim.

Also worth noting: he is pretty knowledgeable about IDEs too. Why do you think he isn't?

Finally, I wouldn't count on Grok being canceled.
