Just to point out -- hypertext systems prior to the web almost universally expected permanent stable addresses (and this was, for instance, required by the various Xanadu specs). Enquire (Tim Berners-Lee&#x27;s immediate predecessor to the Web) had permanent stable addresses, too.<p>The web didn&#x27;t have permanent stable addresses because the web was a hack, intended as a way to explain Enquire to people who didn&#x27;t have a background in real hypertext systems. (Let the entire existence of the Web, with its myriad flaws, be a lesson to you: your crappiest demo may well become the thing you&#x27;re known for twenty-five years later, so make sure your crappiest demo doesn&#x27;t suck as bad as the Web does.)
