@koen_hufkens html and email especially are quite limited technically. I think their staying power (some 40 years and counting) stem not from any individual technical capabilities, but from an architecture that embraced interoperability and federation from the ground up (proprietary email existed before SMTP and is now long forgotten). 20 years from now, will we keep using Google search? Doubtful given #LLMs, but even that aside, there is a marked trend of worse Google search results.
