I agree, but that will not be new either. 
"Being" is in the title of some famous philosophical treatises. 
("Sein und Zeit", L'Etre et le Néant") :-).

But more worrying is that some opinions simply ignore the fact that 
there is more than a century of scientific literature on the 
accommoation-convergence issue. I have uploaded only one figure, but 
it is from a recent authoritative textbook.
