The general public doesn't care to understand the difference between "LLM" and "ChatGPT" any more than they care to understand the difference between "web browser" and "Chrome". Most people will happily use whatever you put in front of them, and if the product is bad, they'll generally grumble and shrug their shoulders in learned helplessness rather than do the research necessary to switch to a better alternative. Discerning consumers are a rounding error. Which is to say, the platform holders will determine who wins and loses. ChatGPT will win if they pay sufficient fealty to Microsoft, Google, and Apple.
