I learned to code without any sort of syntax highlighting or autocomplete features. Whenever I need to use an editor that has Features like syntax highlighting and autocompletion, my workflow actually slows down pretty substantially. The negatives just don't beat the positives for me. Why the negative comments with some folk even calling this guy wrong on an opinion piece? Sheesh, people..
