The AWT could be proposed before one hundred years without problem, because it's simple and it doesn't depend on mainstream physics inventions and theories - only physics of Victorian era.

Now that's REALLY an interesting point Zephir, though it seems to imply that we are discovering rather than inventing I think. Does this in turn mean that we are building on the past, or is this a completely new way of thinking about semantic shift?

I find the example of apples ---- edible red fruit---etc quite an novel way of understanding this whole subject!! Most of the time I am way out of my comfort zone.
