Pixel space is the ultimate IO surface between computers and humans — everything that isn't auditory or tactile ultimately gets flattened to raster images before it's consumed by our senses. It feels like a big part of my job in AI interface design these days is collapsing the layers of abstraction between pixel space and deep models' representations.

Most notable among these layers of abstraction in between pixels and raw information is writing, from written natural language to notations. The best notations flatten key operations to transformations in the pixel space.
