yeah... and it's (partly) based on the claim that it has network effects like how Facebook has? I don't see that at all, there's basically no social or cross-account stuff in any of them and if anything LLMs are the best non-lock-in system we've ever had: none of them are totally stable or reliable, and they all work by simply telling it to do the thing you want. your prompts today will need tweaking tomorrow, regardless of if it's in ChatGPT or Gemini, especially for individuals who are using the websites (which also keep changing).

sure, there are APIs and that takes effort to switch... but many of them are nearly identical, and the ecosystem effect of ~all tools supporting multiple models seems far stronger than the network effect of your parents using ChatGPT specifically.
