“ideas are getting harder to find” seems especially unconvincing outside the hard sciences in domains like music or fiction.

Odd choice for the article to focus on Einstein when this is definitely the case in physics. The lowest hanging fruit has been picked, and reaching the higher branches requires facilities with large collaborations to support them. There are still important ideas coming from individuals, but for comparison the discovery of the photoelectric effect or Rutherford scattering or electromagnetic induction are all things that can be worked out by a single person with a tabletop setup.

It used to be possible for a single person to have all of Physics in their head. Now the amount of information is so large that it's just physically impossible. Physics isn't being created, but uncovered.
