Nitpick. The author is conflating "tab completion" and "autocomplete." The interactions are very different. Tab completion is an active request for information where autocomplete is a prompt or suggestion. Pull vs Push. Google autocompletes your search queries. Bash and zsh offer tab completion as a feature. iPython and Sublime have both tab completion and autocomplete, but they are different interactions.
