It’s coming, Doug. At the present rate of advancement in both electronics and bioengineering, I can imagine a powerful, multifunctional computer/cell phone being implanted in one’s sinus cavity. Then growing an extra occular nerve bundle to connect to it. That way, you can connect with others just by thinking about it and mentally dialing their number. The problem, of course, would be hackers who could log into your computer, then have access to the rest of your mind. The final nail in the coffin of privacy.
That’s my ration of science fiction for today.
