Totally agreed with this. Faces have further to go. We're not out of the uncanny valley yet.
We're also unable to create emergent materials right now, because we don't right now (and may never) have the horsepower to do molecular-level simulation to find out how light interacts with the surface. For similar reasons, breaking something open like an egg, a log, or slicing open flesh is never going to yield truly emergent results. To some degree, they'll always have to be artistically approximated on a case-by-case basis. Those approximations may have increasingly sophisticated interactions as time goes on, but I am reasonably confident they'll never truly simulate things at the molecular level.
