Science is the only discipline that readily admits it doesn't understand everything. You may be confusing it with marketing.
Interesting precision, I have to say. My note began "Well, we will study, study, study..." as I know science does not bring answers to every question. In fact, it seems in the nature of science to encounter unexpected issues while studying a particular problem. These issues will often lead the original study to failure to bring consistent conclusions. The researchers will then positively see them as further questions requiring to be studied.
I actually found that topic contains a part of marketing. Somehow, science has to use marketing tools to promote itself as I was taught quite early in my career that every good study report has to conclude with a sentence like "Our results show interesting areas for further study" which is generally true but also constitutes in real life an appeal for further funding. So, study, study, study...
This report about the technologic methodology used brings no data, nor conclusions at this point. But my main point is that I doubt any lab science will significantly help three hundreds years of acoustic guitar making (with an exception : strings). So, emperor's new clothes...
Lay peoples hope science will answer all their questions. Normal. The problem is many representative figures tend to push science knowledge to row their own boat, bringing confusion instead of light, which reminds me this sentence : Statistics are to politician lamp post for drunk men, they help stand more than they shed light (sorry for the loose translation).
I hope these studies will help, but I am doubful about these.
