Brain implants can allow the paralysed to control robot arms or learn to talk again, but suffer a drop-off in performance when scar tissue coats their electrodes. “An intermediate layer of in vitro neurons interfacing between man and machine could be advantageous,” he says.

Yes, who can say what sort of advantages a neural interface with your computer could provide?  I can only think of about a MILLION.
