(Disclaimer: Google employee, I don’t work on Bard, views my own, etc.) I don’t think either Bing Chat or Bard is ready to be released widely. You need a certain mindset to be able to wring value out of them, and most normal users will not think this way. That being said, it’s probably fine to release these tools to enthusiastic early adopters who understand how to use them.
And yet it will be, because everyone is wowed so we need something out to capture those wowbucks. There are meetings all over the place to figure out "how to best leverage that technology in our product". While there is some value to raise GPT3 as a technology available in your toolbox, these are largely "let's find a problem that this can fix" meetings, and you can bet your sweet ass we'll see GPT in all sorts of stupid maladapted use cases very soon.
