> pretty much everyone I know who is non technical has heard of at least one of those and uses it regularly in their work

Rather than using this as your world-view, I think you should take this as a signal to expand the current bubble you live in. I'm guessing most of these people you refer to as "non technical" are still white-collar workers or similar?

Most people in the world, even with all the marketing towards "non developer business users", has never heard of "Claude", "Gemini", "Grok" or anything else LLM-adjacent like that, but will have some light understanding of "ChatGPT", and might actually be using some AI service via their phone or whatever, but still call that "ChatGPT" as that's essentially synonymous with "AI" in common parlance.
