Even worse, it averages the two inputs, which is a terrible design. One pilot was pushing forward, while the other full back, so the airplane's computer did neither up nor down. Who designs an airplane to operate by democracy? A chain of mistakes combined to cause this accident but bad socialist engineering played a large part.

Ok, genius, how does 'conservative engineering' handle control inputs? Ignore the copilot? What if the pilot passes out and slumps over the wheel? There is a lot of 'democracy' in a redundant system. You don't want any single failure to bring down the plane. If you don't know how these things are designed then refrain from insulting engineers you have never met.

I can't speak for the French but in America two Boeing pilots are trained to have only one pilot in 100% command at one time. There is no 50/50 commune command option. A pilot taking control announces something to the effect "It's my plane" and the other lays off the inputs. If the second pilot does interfere, and especially if they are French or Muslim, the pilot in command has the legal authority, and responsibility, to punch their lights out. Any vehicle designed to operate by secretly averaging the inputs of two co-equal pilots is an accident waiting to happen, and in this case it happened.
