You (and everyone who replied you so far) misunderstood: if you read the article, you'll see that this is not the issue. This is about the reality of trajectories built-into the pilot wave theory (such a concept which doesn't even exist in "text-book" interpretation of quantum mechanics, which says particles don't have positions or trajectories until you measure them, upon which they "decide" their position through an "artificial" process called wavefunction collapse; notably, as of now, wavefunction collapse and the reality of wavefunction is still a subject of debate). There was a paper "Surrealistic Bohm Trajectories" which argued that trajectories predicted by pilot wave theory don't make any sense as real trajectories in general, hence these "trajectories" cannot correspond to real trajectories. A careful analysis which properly takes the nonlocality into account shows the flaw in their argument (arXiv:quant-ph/0010020, omitted in the text linked), and this is the corresponding experiment which confirms their analysis (using weak measurements on a pair of entangled photons to sketch "average" trajectories in a WWM setup). If you like, this is about the interpretation of a concept within an interpretation. While I agree that the title is a little bit flashy, experimental confirmation for the reality of Bohmian trajectories is an important topic.
