That we do, there are still many avenues of physics that have yet to be explored. The article is interesting, but without notation of its source, or any linked experimental data, its nothing more than that. However, it still doesn't claim to explain the underlying reasons or provide a theory of QM. It just allows you to take other form of measurements. The real question, however, is if the experiments result in any more information than can be extracted from the wavefunction. If not, it still only provides a new tool to investigate. Another interesting avenue of research is decoherence, which is the event where the wavefunction collapses. The actual pehnomena occurs so quickly that at first it was though to be undetectable, but modern techniques have been to developed to examine this aspect of qm. In fact, certain moloecules that are normaly to large to exhibit QM effects have produced in a lab which are still bound by QM effect, but on a scale 1000's of times larger than is normally the bound for decoherace. Hopefully, we will be able to learn more about the acutal phenomena of collapsing wavefunction, which would be yet another piece of the puzzle.
