Sure they do.

What if I become really good at summarizing papers for laymen? What if I then start a publishing house for good laymen explanations of science? What if this then leads to the abolishment of all those stupid "Caffeine will give you cancer lololol" articles your mum reads?

Or maybe I'll just learn a lot and use it as an advantage somewhere else.

Or it might inspire people to read more base sources to form informed opinions about things you care about.

And I'm almost certainly not smart and persistent enough for a Nobel Prize.
