No surface anchors in the shared space, Apple probably doesn’t feel confident about this working well. This will be the big breakthrough if it happens, but maybe there’s a reason why we don’t want to start replacing our existing surfaces with digital layers. If your digital objects are anchoring to physical objects, do we run the risk of beginning to feel unsound in our space because we don’t know where our physical surfaces actually begin and end? We still need to know where to sit, and where to lean.
