I mean, I'm not above the feelings the author probably had when he decided to do this.
In most circles, it's at least very interesting to be able to say you have a chip under your skin. It's also a very "cyberpunk" thing to do-- which is to say, not only are you one of the first to have this done (where it could be conceived that a majority may have a similar procedure in the future), but you can now say you're part machine. He does use the term "cyborg".
I can see this looking like a good idea in my own head, just because of its fantasy. At the same time, DAMN, he just put a chip under his skin for absolutely no reason, and on an impulse, without understanding how it works and subsequently locking himself out. Yikes!
I guess we all make mistakes.
