777's must have done many tens of thousands of visual approaches without mishap. It wasn't the airplanes fault, that much is clear.
Political correctnes will not prevent this type of accident happening again. We cannot have pilots that are scared of flying the airplane on a nice clear day. If they are worried/scared is because even they themselves have serious doubts about their ability (or currency). On top of that we cannot have a cultural mindset where a high probability of a crash is preferable to loosing face or speaking out of turn.
A pilot that cannot look out of the window and land an airplane visually on a suitable runway is not a pilot, it does not belong in an airliner. This has to be an absolutely minimum requirement. What would this crew have done if they had to land flaps up? Or gear up? Or in a strong crosswind? Or with unreliable airspeed? Or in many of hundreds of other more demanding scenarios than a visual approach?
The cultural issues are not new and they are well understood, they still need to be addressed. The systems manager versus pilot debate has taken us the wrong path. We have to be pilots AND systems managers. We are droping the pilot bit because it costs money to train and maintain. Accidents cost money too.
