Wow, this is such an improvement over cables...
Since throttle cables never, ever broke
(one particularly scary example ~ 30 years ago, Air France 747 Hull loss when an outboard engine throttle cable broke when the selected reverse - the engine when to full forward overboost and they made a hard right turn off the runway at 117 knots
)
That being said, I do prefer the Boeing way of letting the actual throttle lever position control the engine thrust...
