>“On the other hand, I mean, people have been implanting things into their body, like pacemakers and stuff to control your heart,” he said. “That's a way, way more serious thing than having a small chip that can actually communicate with devices.” People don't get pacemakers for fun. They get pacemakers because they're medical devices that ensure their hearts beat properly.
Don't you think that's what he means by "way, way more serious"?
The point of that quote is to say that putting something unnecessary into your body is a big step, but that it's also a much smaller risk while still providing something interesting.
