Yeah..yeah. It is all rubbish until you actually have to build one that works as advertised. That's the rub! Even if Tao stumbled onto something in the lab it doesn't mean he can translate that into a real product. That type of engineering takes a much different skill set. I doubt any of the previous claims of efficacy were every achievable and certainly they have had enough time to flesh out a host of derivative products during the decade Tao has been on aboard. The fact that they have no working products based on his scientific theory and that current test of the condensate iteration has no been going well, pretty much sums this up. The simple answer is the correct one.
