A lot of people were unclear. Then ending is punchy and clearly supposed to be laden with meaning. The problem is that people weren't clear what had just happened.
Firstly there were the people who we're'nt clear with which way round the implications would be if envelope had contained an interference pattern or a diffuse spread. That's understandable, apparently the magazine had diagrams at the appropriate point in the exposition.
The last line: "a series of shaded semi-circles" put me (and all but 1 of the other commenters) in mind of an interference pattern. Which implies one of at least three things happen next.
However the author apparently meant the opposite, and the envelope contained only a diffuse pattern, which only has a single, depressing, meaning.
