We still know so little about the actual micro scale and macro scale structure and connection graph of the brain. This is a neat advance in tissue integrity but it is not a brain. It's like melting sand into a pile that holds itself and considering it an advance in computing.

Still cool through.

On a side note, the brain is amazing. The more we learn about AI the more amazing it is that the brain emerges from a relatively sparse instruction set, self assembles from widely available local resources, and becomes a general purpose computing engine able to simulate enough of the world internally to promote survival and propagation of its instruction set.
