The hypothesis in the article could be correct (that industry is not adopting new academic innovations because they fail in the real world). Based on my experience in this industry, though, it could just be that there isn't a super strong connection between academia and the people implementing these kinds of systems. I've had many conversations with my academically-minded friends where they're astonished that we haven't jumped on some latest innovation, and I have to let them down by saying that the problem that paper was addressing is super far down our list of fires to put out. Maybe there are places where teams of top-tier engineers are free to spend 6 months every year rewriting critical core systems use un-battle-scarred new algorithms that might have 20% performance improvements, but most places I've worked would achieve the same result for far less money by spending 20% more on hardware.
