One metric will be the interfacing of computing hardware with biological systems. Computing hardware is still way too massive in size. A human red blood cell is discocyte shape, approximately 7.5 to 8.7 μm in diameter and 1.7 to 2.2 μm in thickness. By comparison, the current state of the art in microcomputing was heralded more than 2 years ago when the University of Michigan announced its engineers produced a computer that is 0.3 mm x 0.3 mm - or 300 μm x 300 μm. Getting close but still 2 orders of magnitude too large to go to the Apple Store to drink a bottle of iFluid containing millions of networked microcomputers that can be transported in our circulatory system to interface directly with the nervous system. Meanwhile we have to work with neural implants.

We may not need to interface with the whole brain, just with the right cells to create a wide-enough communication avenue between our brains and computers. So , implants should be enough. As for the computational capacity, the brain is very intricate but, as everything in biology, rather suboptimal in terms of construction; we can simulate some of its primary functions like visual / audio recognition with just a small fraction of computational nodes.
