Thanks for saying this! It's worth pointing out the economic benefit to whoever invents the Next Big Thing -- if they make it compatible with existing conduit, it can just be pulled through replacing existing infrastructure. It turns out the only irreplaceable part is the tubes. Think datacenters, high density offices and apartments, Level 3's long haul links, etc. They will all be looking for a way to pull Next Big Thing like it was fiber.
