They didn’t specially mention NASA in their comment. You know of Thomas Edison and Nikola Tesla, but have you heard of Lewis Latimer? Probably not.
His work was not as significant. Compare https://en.wikipedia.org/wiki/Lewis_Howard_Latimer#Technical... to https://en.wikipedia.org/wiki/List_of_Edison_patents and https://en.wikipedia.org/wiki/List_of_Nikola_Tesla_patents
You know of Watson and Crick, but not Rosalind Franklin. By you, I mean the general you.
