I&#x27;m sure that people at Lyros, AltaVista and Excite were saying the same whilst building their heavy UIs before Google came along.<p>The problem is on-boarding - once the user learns to ask for computer a question then the text (or voice) interface has the potential to be on a completely different level than a graphical interface.<p>Just imagine - instead of searching through a dozen menus for an option you just ask.<p>Hell, that&#x27;s how most people work with Microsoft Office now - fumble around trying to find out where they&#x27;ve hidden the option. Fail. Open Google and type &quot;how to change signatures in Outlook 20XX&quot;.<p>Slack solve that brilliantly - their on-boarding is well designed - the way it gradually introduces features and reinforces concepts is excellent. It reminds me of modern videogames in design.
