His monitor conclusion is a bit silly. There's zero cost to having an extra monitor if you turn it off when you don't need it. When coding I use Emacs like a tiling WM and like to have every relevant file visible, which sometimes means overflowing onto a third monitor. M-x writeroom-mode[0] on a single monitor is perfect for writing, but you can just reach out and turn the others off, or use them for non-distracting content like references or notes in a scratchpad.
