I don't think Google wants to recreate a GPT chatbot. Perhaps a conversation mode information retrieval interface, but not something you'd chat with. It would be more inline with their theme.
It seems to be ok, but as with other LLMs, can "hallucinate", though sometimes it provides sources to its claims, but only sometimes. If it works out, it could be very nice to Google I would imagine.
If they don't want to, it'll be the beginning of their downfall. A bit like Sears not wanting to deal with the web. GPT4 has replaced a lot of my Google search usage and it's only bound to increase as the models get better.
