I think you're both arguing different things:

jlgreco: vi/vim is an efficient text editor when you learn it! And even more efficient with a foot pedal! Don't discredit our time spent learning vi/vim when it is in fact an efficient text editor!

robomartin: vi/vim may be an efficient text editor, but in the grand scheme of a large(non-trivial) project, small improvements to text editing efficiency are irrelevant. Particularly at the sake or cost of learning and mastering vi/vim. There are easier-to-learn and more-intuitive text editors available now.

Both valid points.
