Scott Adams, creator of Dilbert, runs a pretty interesting, wide-ranging blog. Today, he's musing on the different between a cyborg eyeball and an ordinary iPhone:
Technically, you're already a cyborg. If you keep your cell phone with you most of the time, especially if the earpiece is in place, I think we can call that arrangement an exobrain. Don't protest that your cellphone isn't part of your body just because you can leave it in your other pants. If a cyborg can remove its digital eye and leave it on a shelf as a surveillance device, and I think we all agree that it can, then your cellphone qualifies as part of your body. In fact, one of the benefits of being a cyborg is that you can remove and upgrade parts easily. So don't give me that "It's not attached to me" argument. You're already a cyborg. Deal with it.
Your regular brain uses your exobrain to outsource part of its memory, and perform other functions, such as GPS navigation, or searching the Internet. If you're anything like me, your exobrain is with you 24-hours a day. It's my only telephone device, and I even sleep next to it because it's my alarm clock.
What I need for the next upgrade to my exobrain is a special Dilbert pocket on all of my shirts. It should be located where Dilbert's shirt pocket is, but have a cutout hole for the exobrain's eye, which at the moment is just a camera lense[sic]. As my exobrain becomes more capable, and eventually self-aware, it will want to be able to watch the world with me and whisper in my ear via Bluetooth to my earpiece as needed….
Among other things, my exobrain will recognize faces and automatically cross reference them to Facebook and other social media. Wouldn't it be great to meet someone you have met before and have your exobrain whisper to your earpiece "That's Bob. He's a chiropractor. Judging from his lack of a wedding ring and the way his eyes dilate when he looks at you, he is sexually attracted."
And here are a bunch of prototypes of the technology that he's talking about, already in existence:
