Bioengineers create functioning brainlike tissue

The input/output is in my opinion a much bigger problem. You would have to prevent scar tissue from forming around electrodes which is currently a major issue with all MMI in real life. Also the interface would need a way to translate analog input into digital output. Finally programing biocomputer is easier said than done.

A recent article in New Scientist listed some possible methods to establish links between electronics and nerve cells; some of these require genetic or somatic modification to the interface cells.
