It can be said to be speculative, but if the model can explain everything in the world of phenomena, including things that are not explained by particle physics, then, by the same token, so can particle physics. What we need is for the theory to be put to paper and then simply confirmed by a lot of people. Then people will start to develop new technology with the things that it can explain and by that point no one would say it's not confirmed. But I have found that there are societal and psychological issues which prevent many people's confirmation of the basis of my supposition.
