I disagree strongly with the author's pull-quote that "We know nothing more than Bohr, Einstein, Schrödinger, and Heisenberg." There has been roughly a century worth of experiments since the quantum theory came into being. Those experiments have scythed through myriad attempts to explain the mechanism by which quantum theory apparently describes reality. Physicists can choose between interpretations of quantum mechanics according to "taste" precisely because there are no observable ways to differentiate between them. As soon as those ways become available to us, "taste" will give way to experimental tests. There is still ample room for cleverness. Experimentalists are pushing forward where we can, but another observation like Bell's might be sufficient to allow, pardon the pun, a quantum leap.
