I agree, Quanta booted the title. A more accurate title appears to be A proof of the Erdős primitive set conjecture (Arxiv preprint).

I found a description of the conjecture online:
A subset of the integers larger than 1 is primitive if no member divides another. Erdős proved in 1935 that \sum_{a\in A}\frac{1}{a\log(a)} for a running over a primitive set A is universally bounded over all choices for A. In 1988 he asked if this universal bound is attained for the set of prime numbers.
