GP was criticizing having entire teams including team leads who are too young to have much experience, when there are people around who do have that experience.

How do you get from that to "Delaying this to an older age"? > Circa Apollo 11 the average age of a NASA engineer was 28. In 2009 it was 47. That has absolutely nothing to do with "treating people like children at continually older ages" Circa Apollo 11, the average age of the American population was 29. Today it is 38. In addition to that, NASA had its budget increase over 1000% between 1960 and 1965, so it had to hire a lot of new people for doing something nobody had done before. That is a very different situation than in 2009, when its (inflation adjusted) budget was around half the peak and had been slowly declining for almost 20 years. You don't hire a lot of people in that situation, so your workforce automatically ages.
