In a plane, the power window would have an "In case of emergency, break glass and turn crank to lower window" was all I was getting at. . . .this kind of thing is akin to my amusement at a friend bringing a 4TB "media Server" to my house once, and not being able to use it because he'd forgotten the remote, and the unit itself has no buttons on it.
Indeed, I suspect that even if getting an RFID chip implanted in your left wrist becomes a method of payment today, it'll take decades to take over, and people will still take credit cards and cash for decades after that.
The most likely place to see it become universal would be something like fighter pilots, where quick reflexes and tough environmental conditions might make it such a huge advantage to have the pilot completely restrained in an anti shock jell filled egg in the cockpit, with all sensory data and commands executed via implant. (The only reason to put a pilot in the plane at all is to avoid jamming control signals). . .I could see the potential for that job becoming an "If you don't have an implant, you no longer get to perform combat roles." kind of thing. . . .
Most jobs likely not. . .though it may become such a competitive advantage as to make most convert. . .then again, most of those "quick response" roles would be under competition for improving AIs. . .like putting a brain implant in a stock trader is not going to let them keep up with the nanosecond transaction times of the current "expert machines" in terms of fast trading strategies, for that application it's not just the ability to give commands that has shrunk the response loop down, the machines are making choices way faster than any human ever could.
