My take: this is the making of a great essay question for a graduate course in networking. The chance of TCP being thrown out wholesale is zero. What might happen is some slow, incremental improvements in certain aspects of networking, like some other comments suggest. Until eventually, a networking student picks up a dusty old TCP doc and says to his teacher, innocently, "But we're not doing hardly any of this stuff anymore!"
