What are you talking about? "porn stars" in this context refers to (at least somewhat somewhat) widely known performers in sex movies. There were no mainstream movies back then, 'movie actor' wasn't a profession yet, and there was no way to become famous by doing outrageous sexual activities and exhibiting them to a broad audience. In fact in most of the world one would be thrown in jail for showing in public what is nowadays shown on prime time tv.
So, once again, it's ridiculous to suggest that porn actors are less important than scientists only supported by the argument that nobody remembers porn actors from that time. There weren't any!
(note that I'm not saying that one is more important than the other, I guess it depends on the definition of 'important', I don't know nor care - frankly I find the question quite trite and boring. My point is merely that the argument is ridiculous.)
