Although it makes a lot of sense to me and a lot of others, trust me, it's not irrefutable to everyone.

Obviously not!! I don't suppose the work done by Dr. Ashby is perfect. But then again, once upon a time the best theory available was that the world was flat. Until a better theory came along, it seems like the reasonable theory to subscribe to. Likewise to Dr. Ashby's work, until something better comes along it seems like a reasonabletheory (although the use of the word theory is out of context in this case) to subscribe to.
