With the caveat that I'm not a machine learning expert, my understanding is that there can be a lot of manual tweaking that goes into building neural net models. Whatever OpenAI is doing with ChatGPT is not something Google has been able to replicate with Bard. And I don't think that's for a lack of trying. I don't mean to come off as a doomsayer for Google, I'm really not, but I don't think Google's success here is inevitable.
