the physical mechanical throttle cable/linkage versus throttle-by-wire debate rages on. a computer belongs on your desk top but not in your car. once computers were introduced to automobiles, things began to go wrong in a hurry. simple designs tend to be more fail safe, while complex, complicated designs tend to screw up. drive-by-wire, brake-by-wire, text-message-by-wire, no-thanks-I'll-take-the-bus-by-wire.

overheard on the intercom system aboard the world's first totally computerized aircraft:

Computer Pilot: "Ladies and Gentlemen thank you for flying electron airways, home of the world's first totally computerized aircraft. Our aircraft has been outfitted with the most modern, sophisticated flight
computers the world has ever seen, therefore no human pilots are required and none are on board this flight.

Lest any of you have concerns over safety and reliability aboard this modern day aircraft, let me assure you that nothing can go wrong, go wrong, go wrong, go wrong, go wrong, go wrong, go wrong, go wrong, go wrong, go wrong........"
