Per wiki on Apollo
> Landing humans on the Moon by the end of 1969 required the most sudden burst of technological creativity, and the largest commitment of resources ($25 billion; $182 billion in 2023 US dollars)[22] ever made by any nation in peacetime. At its peak, the Apollo program employed 400,000 people and required the support of over 20,000 industrial firms and universities.[23]
Different budget, different number of people working on this stuff and different mindset. Actually the Apollo program was also iterative and it paid off.
