There is no need to do this. Carry a cellphone? They got perfectly fine ways of tracking you. The next step is wearable technology like Android and iOS watches and after that we will see humans merge with machines…
I cant imagine it now but I dont completely rule out to use bionic replacements of body parts once I get old if it is affordable by then. Getting a Google chip or similar is more unlikely because I wont need to compete with other people just starting their working career and trying to get an edge over the competition.
Anyway, lets see how long our technological world exists as we know it now.
