I think the "it just FAILED" assessment is a little simplistic. The AGC worked fine in all other mission phases and it was a systematic absence of testing the actual landing radar in Apollo 11 (they tested in a different mode in simulation without real hardware) that was the issue during descent. Chalk another one up to complex components leading to unexpected behaviors when integrated in the wild. In any event, the reason ALHAT and precision autonomous landing are technology efforts is because no one has demonstrated a production system to do these things.
