This is such an absurd statement. What US aerospace has created post 1969 is nothing short of remarkable in comparison. (And we can be proud of the Apollo era too.)

What are you referring to?
If you want to chart progress over time, consider this: In 1919, people were still flying biplanes and civilian aviation barely existed. Fifty years later, in 1969, you've got the 747 -- consider the progress made over those fifty years! Fifty years from then, in 2019, you've still got the 747 -- alongside, as the article notes, smaller and less remarkable aircraft "that are more efficient, but far less majestic and memorable."
The efficiency and the safety. Modern planes are disgustingly safe to the point that hull loss is almost unheard of. For 50 years the industry has optimized for safety and fuel efficiency. And the modern machines are marvels in that.
True, but still incremental improvements over proven designs - maybe a sign of very strict safety standards making new designs and differentiation more expensive than just the development.
