The NASA scientists went on and revolutionised the tech and manufacturing industry after the lunar landing. I'd hardly say this is a case of technological supremacy reverting, rather the opposite. The technical expertise developed thereof had massive benefit for US tech and industry sectors.

In terms of societal benefits, the lunar mission had an extremely high cost for little direct benefit. The moon landing was an effort in propaganda, and an effective at that, aimed to show the world that the US was not lagging behind the USSR in terms of technology. But it would have been foolish to go on and continue to spend such a massive amounts of money, and hogging the best scientists and engineers for decades more, with hardly benefits other than ideological ones.
