I&#x27;ve always found it quite curious that computer human interfaces have always focused on the noun&#x2F;verb proposition of describing data, and not the time&#x2F;place.  Time is the only true constant in the universe, and yet computers are set up to track and control it, seemingly, as a second thought.<p>Imagine if instead of having files&#x2F;folders to (teach,confuse) Grandma, we simply had a time-based system of references.  If Time was a principle unit of information that a user was required to understand as an abstract concept, I feel that it would result in far better user interfaces.<p>We can see this in the Music-making world, where Time is the most significant domain over which a Musician exerts control.  A DAW-like interface for managing events seems to me to be quite intuitive - for so many other non-musical applications - that its almost extraordinary that someone hasn&#x27;t built an email system, or accounting system, or a graphical-design system, of applications, oriented around this aspect.  (Of course, they are out there - but it seems that Time management makes the dividing line between &quot;professional&quot; and &quot;dilettante&quot; users rather thick...)
