I think what I would add to your comment, and specifically criticize the HN hype around it, is that all these GPT "AI" tools are entirely dependent on the OpenAI API. ChatGPT might have shown a glimpse of spark by smashing two rocks together, but it is nowhere near being able to create a full-blown fire out of it.

Outside of Google and OpenAI, I doubt there is a single team in the world right now that would be capable of recreating ChatGPT from scratch using their own model.
