I use Claude. I use Codex. I've never heard of or used Meta AI. Nor do I have a Facebook account. Never have, never will.
I am also a software developer. So while the numbers of "people" that use one AI or another may be higher than either of these, it's not a useful metric for myself.
That's fine. I'm not making a value judgement about which LLMs you should use, if any.
I'm only pushing back against someone thinking "oh HN talks about Claude a lot, therefore Claude must be extremely popular". The information bubble is a real problem.
