Yeah I grok it. What I mean was, you can get 95% of the benefits of an RFID implant with a simple wearable like a rubber bracelet. If you wear it all the time, after some time you plain forget about it, and you’re not likely to lose it. But it’s not cool, and for those of use who can’t stand wearing watches of jewelry, it’s not an option.
Also, yeah, I’d love a direct interface to my brain - audio, video, controls, whatever - that I don’t need an external bit of kit for, and that I never need to charge. But that’s still science fiction. I have to settle for what’s available.
