I've been using a manual transmission ever since I took my driver's license 10 years ago. At first I also drove a shitty car ... gears wouldn't shift unless you knew how to touch the gearstick :)
Now I can drive just about anything, with no accommodations necessary. Changing gears is also in my reflex and it doesn't bother me ... I just don't think about it. I can also eat a sandwich or talk to the phone with no hands-free while driving, although that's considered a bad practice that's also illegal :)
People who never drove a stick-shift may have no idea how to operate one. Whereas someone switching from an IDE to a text editor would still be able to work - just less productive.
I have my doubts about that as I have seen many evidence to the contrary.
Technology is great. Embrace the future!
