This thread is now becoming extremely silly, in the words on Monty Python.
Why should there be changes to the AB system just because it appears that there was extremely poor training / airmanship. If you only close one thrust lever with two engines running and you are not ready to stamp on the manual brakes if the the autobrakes fail to operate on a short field landing, in marginal conditions then it is not primarily the fault of the aircraft or its design.
