The TCP and IP protocol specifications do not mention routing either. There are many routing algorithms possible, and many of them are used simultaneously. The same will be true for the lightning network. Lighting has a long way to go, but writing it off as a cute but useless experiment because of current limitations is short sighted.

TCP/IP based networks don't have rapidly changing topographies. A payment channel network's topography changes every time it processes a transaction, because it changes the amounts available for transferring in the channels that transaction was routed through.
