It’s a long way away. Assuming it will be based on MRI imaging of axons/neurons etc., the resolution of the current state of the art is too low. There’s no foreseeable advances in this area, so the only hope is a paradigm shift or serious breakthrough. The Human Connectome Project might interest you. It is the closest thing we have to this right now. Also the Open Worm project. We have successfuly uploaded nematodes (by countless dissections and microscopically mapping the neuron/axon connections).
