TikTok, Facebook, Instagram, etc. have network effect stickiness. YouTube has a vast library that grows in value over time and has been able to lose money for long enough to make the experience unassailable, etc. (Look at Vimeo.)
Maybe LLMs get that by knowing our entire past? But I find that creepier than useful. Right now ChatGPT is at the top of the world, but I don't see it becoming the new unrivaled Google Search. There's just too many people building it, and once OpenAI starts monetizing and "enshittifying" it, other offerings will become more compelling.
AI models put a large swath of mostly tech companies at risk. Including the old business models of titan products like Google Search.
Image/video/world models specifically do this more to legacy media incumbents than LLMs do to complex business processes. We see orders of magnitude savings with marketing, design, film, and possibly in the future game design. LLMs, on the other hand, aren't great at getting your taxes or complex business logic right.
