Take a look at the command and lunar module computers—there was no way they could possibly work—and NASA knew it. That meant navigation became impossible once the communications delay from Earth kicked in.... (four seconds each way to the Moon) which in turn would mean certain death for the astronauts:

That is complete nonsense. It's even factually wrong. Just divide 250000 (distance earth-to-moon in miles) by 186282 (speed of light in a vacuum in miles per second). You get about 1 1/3 seconds. Round-trip it was about 2 1/2 seconds.

"Navigation becomes impossible" with a 2 1/2 second roundtrip comms lag? Why?

A few seconds and a wrong turn and you are dead—”cold equations”.
