Deep learning and robotics qualify as far fetched tech? Anyone with a laptop and one of a dozen open-source frameworks can get started with deep learning today. Rendering a 3D object that blends in real time with a person's perspective of their physical environment and beaming it directly into their retina seems far more far fetched.

Perhaps the deep learning using robotics is simply related to this larger task, for example controlling the projecting element to account for retina movement or something similar.
