It has been mentioned multiple times here that no matter how good a sensor it can fail. E.g. a bird can take it out or something else. The problem seems that it is only dependent on a single sensor which is very dangerous. It should be connected to at least two sensors so if one fails it doesn't send out a false positive signal to aim the plane down to the ground. Instead it would just give a sensor fault message and the flight continues. A computer can only calculate as good as the input it gets. Most planes today have triple redundancy on input.
