3D printed stem cells to treat neurological conditions?

Technology is running ahead so fast now and sure it's great if your inflicted with a condition and become well again but as always there is the possibility it could be used for brain augmentation to become more intelligent or hard wired biologically for a Cybernetic connection hardware and have access to g-d knows what!

According to the project partners, the development of human 3D neuronal networks that exhibit physiologically relevant and reproducible architecture and activity could be “foundational” to the scientific community, enabling large-scale scientific investigation of human brain network function.
