<p>[QUOTE="fatima, post: 1435067, member: 22143"]Really? The entire point of replacing mechanics with electronics is to remove the materials costs and add features. How many 10s of millions of land line telephones were around then compared to now. How many millions of pay phones were displaced by mostly plastic cellphones? One of those phones had more metal in them than 25 cell phones. I would also say there are LESS passenger jets now than back in the days when that video was produced. An "advanced car" means it has less metal in it now. </p><p><br /></p><p>The point being relative to electronics driving demand of silver is that electronics reduces the need for materials including materials such as PMs. One of those #5 crossbar switches had tens of thousands of mechanical relays in them, each with a coating of PM to reduce corrosion. The electronic switch that replaced it has no relays.[/QUOTE]</p><p><br /></p>
