Of course. But even then this technology wouldn't cause the price of lenses to necessarily drop "like a rock". The lens material is just part of the entire food chain, and a lens isn't necessarily comprised entirely of elements made from silica glass.
Never said that they would. R&D makes up a good amount of a lens, and things like that will always factor into the price by the time it hits the shelf.
Only disagreeing with the notion that companies will be able to hold prices constant, despite significant decreases in the cost of raw materials and the cost to manufacture each lens. In any competitive market, decreases in the cost to manufacture a product will have a corresponding decrease in the cost to the consumer (prices will move to equilibrium). Does that mean a $450 lens will sell for $5? Of course not. But if this technology pans out (very big if), it would not be unreasonable to expect a $450 lens to drop to something like $250-$300 for a comparable lens with silica elements.
