I really hate the corner of the tech industry that takes old ideas and renames them and then goes &quot;hey look at this new trendy idea I thought of!&quot;.<p>Just because you move the user interface off the screen and into physical space doesn&#x27;t make it &quot;Zero UI&quot;. People have been designing ways to interface with machines in physical space ever since somebody figured out how to put a handle on a rock and make it a hammer.
