Fake. He talks about 10g, which we're not even close to, and then 4g. Neural interfacing is extremely complicated and won't have a breakthrough within a couple years. Also you can't insert a common DIP chip into your brain and expect it to work. For a neural interface, it would require millions of nano fiber wires across the brain. A brain doesn't respond to wifi, so coating part of the chip with a little gold paint won't do anything.
