I have never, in THIRTY years of designing hardware and writing software, been slowed down by a text editor of nearly any kind (other than the first time I used VI). And, yes, I can use vi and vim. And yes, I think it is total horse-shit. The things that have slowed me and others down, caused projects to fail, caused robots to crash and damage something or caused the success or failure of a business have been orders of magnitude removed from any advantage that could be had via a text editor, even if it was wired into my brain.
It is OK to make oneself believe that this is really useful stuff. Some people believe in all kinds of invisible things. And, in that context, anyone going against those beliefs is a lunatic. I am, on more than one front. I prefer to focus on what is real and what is significant.
