This only means that the web (websites and web 2.0 platforms) for public usage is becoming redundant because any type of data that can be posted on the web can now be generated by an LLM. LLMs have been only around for a short while but the web is already becoming infested with AI spam. Future generations that are not accustomed to the old pre AI web will prefare to use AI rather than the web, LLMs will eventually be able to generate all aspects of the web. The web will remain useful for private communication and general data transfer but not for surfing as we know it today.

Edit to add:

Projects like the Internet Archive will be even more important in the future.
