I'm happy to make that argument. LLMs were experimental in 2023. It's 2026 now, and enormous numbers of people use them on a daily basis (ChatGPT has 1.2 billion weekly users now, according to Sam Altman at OpenAI DevDay).
They're only experimental in the way that computers are still experimental, since we continue to find new ways to use computers.
I think that's shaky but also that's OpenAI and not Meta. Up until whenever Muse was launched Meta didn't have anything I'd call a LLM product.
