Implants like this aren't going to catch on any time soon IMO, at least not for non-medical reasons. It sounds cool and all, but with current medical technology, implanting a device into your brain is a pretty invasive procedure. A lot of risk for no/little gain. Unless they can think of some kind of creative way to implant something in the brain without drilling through your skull, this will never catch on. Or maybe the chips will be small enough that a very small (microscopic?) hole could be drilled in the skull, and it could be implanted through that.
Devices placed under the skin or something like that seems a lot more practical, though.
