idk, I personally think if you need that kind of deep learning in your code then you are repeating yourself too much. I wrote a 30k line project with sublime and never faced any issues. Everything is as snappy as it was at 1k lines. Never needed intellij level code context awareness. I also worked on some android app some time ago and I probably could not have gone far without intellisense. So I think it depends on the language. Java is a lot more verbose than say php or javascript.
