I'd like to pick on the word 'invisible': if the user can get into a flow state with a tool where work becomes the major focus. I can argue that you can get into that state with any tool with enough practice. And sometimes that's only possible if the tool is actually visible to you as in all graphical UI bits you need are exactly where you remember them to be, exactly where your motor reflexes immediately seek and find.

So regarding proficiency. I bet you weren't as proficient with multiple cursors and all the things you can do with it when you first used it. (15 years is a long time to remember how it all started.) I could argue that all the key shortcuts and other bits you need to make multiple cursors work effectively doesn't come to everyone instantly. But with time you could and would hit that level.

Overall tho, vim is an interesting comparison to make also because sublime text also has a 'vintage mode'. I personally use it with vim shortcuts enabled. it lets me use vim motions on top of everything sublime offers. Does sublime + vim make it more 'invisible' to me than it is to you?

I generally have issues with arguments like this. It starts with a sexy phrase that projects some earned wisdom but then the rest of the supporting arguments are forced into the narrative most of the time by selectively ignoring important information. You could have just said I love sublime and I prefer it over vim because of this and that. or it could have been a direct critique of linux desktop. they would all stand on their own, even better I would argue, without being shoehorned into an overarching, simple, catchy phrase.
