There is a lot of basic airmanship which has failed here. For example from your first day of PPL training you are taught to backup the throttles during takeoff and at low altitude to avoid them creeping backwards. You are also taught to cross check that you've achieved half the rotation speed at 1/3 of the runway available. Obviously these practices are less applicable to an airliner but the basics are still there. The pilots should be monitoring engine performance and acceleration to avoid these type of issues. In this case it was a software bug but it would be just as easy for it to have been a wrongly input takeoff weight or temperature to affect the calculated TOGA power.
