Well of course token ring architectures, like those used in massively parallel relational databases have never used TCP/IP. But for the most part, the seven layer (originally 4 layer) OSI model is still intact. The entire World Wide Web made a very graceful transition to IPv6 about 10 years ago and the whole standard continues to evolve with special headers, point-to-point-tunneling protocol, etc.
Actually, network evolution is one of the smoothest most sensible foundations of the cyber universe. To be sure, Telnet is dead. My telnet manual is in the same junk drawer as my plastic slide rule from the sixties.
When did you first start using the internet?
